DF-1 cells culture: DF-1 cell line of chicken embryo fibroblast were cultured in DMEM (Gibco, USA) supplemented with 10% (v/v) fetal bovine serum (FBS, Hyclone, USA) and 0.2% penicillin/streptomycin (Invitrogen, USA).
QM-7 cell culture: QM-7 cell lines of avian myogenic origin were cultured in high-glucose M199 medium (Gibco, USA) with 10% fetal bovine serum (FBS), 10% tryptose phosphate broth solution (Sigma, USA), and 0.2% penicillin/streptomycin.
CPM isolation and culture: Primary myoblasts were isolated from the leg muscle of 11-day old chicken embryos. First, the muscle tissues were dissected away from the skin and bone, and then homogenized in a petri dish. To release single cells, the suspension was digested with pancreatin for 20 min at 37 °C. After neutralization with complete medium, single cells were collected by centrifugation at 500 × g. Subsequently, serial plating was performed to enrich for primary myoblasts and eliminate fibroblasts. Primary myoblasts were cultured in Roswell Park Memorial Institute (RPMI)-1640 medium (Gibco, USA) with 20% FBS, 1% nonessential amino acids, and 0.2% penicillin/streptomycin. The differentiation of myoblasts was induced by RPMI-1640 medium supplemented with 0.2% penicillin/streptomycin.
All cells were cultured at 37 °C in a 5% CO2 humidified atmosphere.

To determine the acid tolerance of strains, LAB cells were harvested by centrifugation at 6000 g for 15 min after incubation at 30°C for 48 h. The collected pellets were suspended in sterile PBS (phosphate-saline buffer; 9 g/L NaCl, 9 g/L Na2HPO4·2H2O, 1.5 g/L KH2PO4) adjusted to pH 2.5 to the initial volume. The mixture was then incubated at 37°C for 4 h. Aliquots of samples were taken at time 0 and after 4 h. These samples were serially diluted in sterile saline solution (0.85% NaCl) and the viable cell population was determined by the spread plate method using MRS Agar. The plates were incubated at 37°C for 48 h [13 (link)]. The percentage survival of the bacteria was calculated as follows: %survival=log  cfu  of  viable  cells  survivedlog  cfu  of  initial  viable  cells  inoculated×100. For the bile salt tolerance assay, MRS Broth containing 0.3% (w/v) bile salt (oxgall) was inoculated with active LAB cultures (incubated at 30°C for 48 h) at an inoculum size of 1% (v/v) and incubated at 37°C for 4 h. The viable cell population was determined at 0 h and 4 h of incubation on MRS Agar plates by the spread plate method. The percentage survival of the bacteria was calculated according to (1) [14 ].
To test the viability in the presence of pepsin, simulated gastric juice which was prepared by suspending 3 mg/mL pepsin in sterile saline solution (0.85% NaCl, w/v) adjusted to pH 2.5 was inoculated with active LAB cultures (incubated at 30°C for 48 h) at an inoculum size of 1% (v/v) and incubated at 37°C for 4 h. Simulated intestinal fluid which was prepared by dissolving bile salt (0.3%) and pancreatin (1 mg/mL) in sterile saline solution (0.85% NaCl, w/v) adjusted to pH 8.0 was used in pancreatin resistance test. This fluid was inoculated with active LAB cultures at an inoculum size of 1% (v/v) and incubated at 37°C for 6 h. The viable cell population was determined before and after incubation on MRS Agar plates by the spread plate method.

Ventricles were dissected from neonatal (1–2 d) Sprague-Dawley rat hearts and dissociated by serial digestion with 0.4 mg/ml collagenase and 0.6 mg/ml pancreatin sterile digestion buffer (116 mM NaCl, 20 mM HEPES, 0.8 mM Na2HPO4, 5.6 mM glucose, 5.4 mM KCl and 0.8 mM MgSO4, pH 7.35). The first digestion supernatant (5 min, 37°C, 160 cycles/min in a shaking waterbath) was removed and discarded. Cell suspensions from subsequent digestions (20 min, 2×25 min, 20 min, 10 min; 37°C 136 cycles/min shaking) were recovered by centrifugation (5 min, 60×g) and the cell pellet resuspended in plating medium (Dulbecco's modified Eagle's medium (DMEM)/medium 199 [4:1 (v/v)], 15% (v/v) FCS, 100 units/ml penicillin and streptomycin). The cells were pre-plated on plastic tissue culture dishes (30 min) to remove non-cardiomyocytes. For biochemistry and molecular biology experiments, non-adherent viable cardiomyocytes were plated at a density of 4×106 cells/dish on 60 mm Primaria dishes pre-coated with sterile 1% (w/v) gelatin (Sigma-Aldrich UK). After 18 h myocytes were confluent and beating spontaneously. For immunostaining experiments, cardiomyocytes were plated at 1.5×106 cells/dish on 35 mm Primaria dishes containing glass coverslips pre-coated with sterile 1% (w/v) gelatin followed by laminin (20 µg/ml in PBS; Sigma-Aldrich UK). The plating medium was withdrawn and cells were incubated in serum-free maintenance medium (DMEM/medium [4:1 (v/v)], 100 units/ml penicillin and streptomycin) for a further 24 h.
Cardiomyocytes were unstimulated (Controls), exposed to PD184352 (2 µM), a cell-permeable form of the exoenzyme C3 transferase from Clostridium botulinum (C3T; 1 or 5 µg/ml) or ET-1 (100 nM), or exposed to ET-1 following pretreatment with PD184352 (10 min) or C3T (120 min). PD184352 (Alexis Biochemicals, Enzo Life Sciences) was prepared as a stock solution in DMSO (4 mM). Cell-permeable C3T (Cytoskeleton Inc., Cat. no. CT03) was resuspended in 66% (v/v) glycerol (0.02 mg/ml). This represents highly purified C3T linked to a cell penetrating moiety though a disulfide bond that allows rapid uptake into cells. In the cytoplasm, the disulfide bond is reduced and the C3T diffuses through the cell. ET-1 (Bachem UK) was prepared as a stock solution in water (0.1 mM). ET-1, PD184352 or C3T were added directly to the tissue culture medium. Unless otherwise stated, incubation times with ET-1 were dependent upon the time at which individual signaling components are substantially activated: 30 s for RhoA.GTP loading [25] (link), 5 min for activation of ERK1/2 [26] (link) or p38-MAPKs [27] (link), 15 min for activation of JNKs [28] (link) and 1 h for expression of immediate early genes [10] (link). For inhibitor studies, cells were pre-treated with inhibitor for a minimum period required to provide adequate inhibition of the pathways (10 min for PD184352; 2 h for C3T) prior to addition of ET-1 for the appropriate times. Cells were also exposed to inhibitor alone for the full duration of the incubation time. All samples were harvested together at the end of the experiment.

Example 5

The Lactobacillus ingested through the oral cavity passes through the stomach with the lower acidity and the intestines with high digestive enzymes and are exposed to low pH of gastric acid, pepsin, intestinal bile salts and digestive enzymes. Therefore, in order to utilize microorganisms as probiotics, gastric juice resistance is essential to survive in low pH and enzymes, and bile juice resistance is essential to survive in extreme intestinal environment. In accordance with the present disclosure, experiments were conducted to identify resistance to artificial gastric juice and bile juice of the above two strains with superior inhibitory effects against Gardnerella vaginalis and Candida albicans. The pH of the gastric juice in the body is maintained at about 3.0, and the food passes through the stomach for about 3 hours. In general, when maintaining viable cell count for 3 hours or more at pH 3, the cells has the high resistance to acidity. In order to identify the intestinal viability of Lactobacillus, survival experiments for artificial gastric juice and artificial bile juice were conducted with reference to Maragkoudakis' method. MG4272 and MG4288 strains were streaked on MRS plate medium and incubated at 37° C. for 24 hours, and the resulting colonies were inoculated in MRS liquid medium and incubated (37° C., 24 hours). Then, 2% passage was incubated for 24 hours in fresh MRS medium. The culture medium was then centrifuged (4,000×g, 4° C., 5 minutes) and washed twice with phosphate-buffer saline (PBS, pH 7.4). The washed cells were adjusted to OD600 1.0 (108 to 109 CFU/mL) and used for resistance experiments to the artificial gastric juice and artificial bile solution, respectively. As a control, 900 μL of pH 7 PBS was added to 100 μL of diluted Lactobacillus and the mixture was shaken and the number of viable cells was measured immediately. In order to identify the resistance to gastric juice, pepsin (Sigma-Aldrich, Saint Louise, USA) was dissolved in 3 g/L of pH 3 to pH 4 PBS to prepare an artificial gastric juice. 100 μL of lactobacillus diluent was added to 900 μL of artificial gastric juice, shaken, and cultured at 37° C. In 3 hours, the viable cell count was measured. To identify resistance to the artificial bile juice, pancreatin (Sigma-Aldrich, Saint Louise, USA) was dissolved in 1 g/L at pH 7 to pH 8 to prepare artificial bile juice. 100 μL of lactobacillus diluent was added to 900 μL of artificial bile juice, shaken and incubated at 37° C. In 4 hours, the viable cell count was measured. The measured results are shown in Table 1 in terms of log CFU/ml.

As shown in Table 1 both strains of MG4272 and MG4288 were identified to maintain the viable cell count of 108 CFU/mL or more after 3 hours at pH 3, thereby identifying excellent acid resistance. In the artificial bile resistance test, both strains of MG4272 and MG4288 were identified to maintain the viable cell count of 108 CFU/mL or more, thereby identifying excellent bile resistance.

EXAMPLE 10

Rhizopus oryzae (RO) lipase displayed far greater activity toward DHA and ARA triglycerides than porcine pancreatin (Zenpep®), which contains a mixture of pancreatic lipases, proteases, and amylases. 1.4 mL of infant formula was mixed with 100 uL of lipase (either pancreatin or RO lipase) and 100 uL each of triglycerides of DHA and ARA. Reactions were incubated at 37° C. for 15 minutes. Samples were taken at time points 0, 1, 2, 4, 6, 8, 10, and 15 minutes and analyzed by RP-HPLC for DHA and ARA. DHA (FIG. 28A) and ARA (FIG. 28B) triglycerides were hydrolyzed by RO lipase over time but were not hydrolyzed by pancreatin.

Mouse E9.5 embryos were partially digested in warm PBS containing 5 mg/ml pancreatin (SIGMA) for 3 min, followed by isolation of caudal neural tubes using fine forceps in ice-cold PBS. The isolated neural tubes was passed through a 27-gauge needle (TERUMO, Tokyo, Japan) ten times to dissociate cells, which were subsequently cultured in a 1:1 mixture of Dulbecco’s modified Eagle’s medium (GIBCO) and F-12 nutrient (GIBCO) containing 0.6% glucose, 5 mM HEPES buffer, 25 μg/ml insulin, 100 μg/ml transferrin, 20 nM progesterone, 60 μM putrescine, 30 nM selenium chloride, 10 ng/ml FGF-2, and 20 ng/ml EGF, as described by Tropepe et al.45 (link). Dissociated cells were seeded onto a collagen type I (Nippi, Tokyo, Japan) coated 96-well cell culture plate (3596, Corning, NY) and cultured for 24 h at 37 °C in a humidified atmosphere containing 5% CO2 and 3% O2. Cells were subsequently fixed with 4% PFA and permeabilised with 0.1% TritonX-100, followed by blocking with PBS containing 10% FBS for 1 h at room temperature. Cells were then incubated overnight with the primary antibody at 4 °C, excess of which was removed by three washes with PBS, prior to treatment with Alexa labelled secondary antibodies. Subsequent to three washes with PBS, immunostained cells were visualized using the high-throughput high-content imaging system Opera Phenix (Perkin Elmer, Waltham, MA), and data were analysed using Harmony 4.5 (Perkin Elmer). On average 342 ± 99 cells were selected as the Nestin-positive cells in each well and mean fluorescent intensity of Alexa in the selected cells was calculated.
