Collagenase

Collagenase is an enzyme that catalyzes the breakdown of collagen, the primary structural protein in connective tissue.
This versatile enzyme plays a crucial role in tissue remodeling, wound healing, and various research applications.
Collagenase is widely used in cell isolation and culture procedures, as it can effectively dissociate cell-cell and cell-matrix interactions, allowing for the extraction of viable cells from tissues.
Additionally, collagenase is employed in the treatment of conditions like Dupuytren's contracture, where it helps to disrupt the abnormal collagen accumulation.
Researchers leveraging collagenase must carefully optimize its use to ensure reproducibility and accuracy in their studies.
The PubCompare.ai platform offers an AI-driven solution to identify the best collagenase protocols from literature, preprints, and patents, helping elevate research efficiency and outcomes.

A schematic overview of the myocyte isolation procedure is shown in Figure 2. An expanded description of the procedure, accompanied with images and videos, and complete materials list is available in the Online Data Supplement, alongside full details of additional methods applied in this study (Appendix A-ix). All animal work was undertaken in accordance with Singapore National Advisory Committee for Laboratory Animal Research guidelines. Relevant national and institutional guidelines and regulations must be consulted before commencement of all animal work.
Buffers and media were prepared as detailed in Appendix D. EDTA, perfusion, and collagenase buffers were apportioned into sterile 10 mL syringes, and sterile 27 G hypodermic needles were attached (Online Figure IA).
C57/BL6J mice aged 8 to 12 weeks were anesthetized, and the chest was opened to expose the heart. Descending aorta was cut, and the heart was immediately flushed by injection of 7 mL EDTA buffer into the right ventricle. Ascending aorta was clamped using Reynolds forceps, and the heart was transferred to a 60-mm dish containing fresh EDTA buffer. Digestion was achieved by sequential injection of 10 mL EDTA buffer, 3 mL perfusion buffer, and 30 to 50 mL collagenase buffer into the left ventricle (LV). Constituent chambers (atria, LV, and right ventricle) were then separated and gently pulled into 1-mm pieces using forceps. Cellular dissociation was completed by gentle trituration, and enzyme activity was inhibited by addition of 5 mL stop buffer.
Cell suspension was passed through a 100-μm filter, and cells underwent 4 sequential rounds of gravity settling, using 3 intermediate calcium reintroduction buffers to gradually restore calcium concentration to physiological levels. The cell pellet in each round was enriched with myocytes and ultimately formed a highly pure myocyte fraction, whereas the supernatant from each round was combined to produce a fraction containing nonmyocyte cardiac populations.
CM yields and percentage of viable rod-shaped cells were quantified using a hemocytometer. Where required, the CMs were resuspended in prewarmed plating media and plated at an applicationdependent density, onto laminin (5 μg/mL) precoated tissue culture plastic or glass coverslips, in a humidified tissue culture incubator (37°C, 5% CO2). After 1 hour, and every 48 hours thereafter, media was changed to fresh, prewarmed culture media.
The cardiac nonmyocyte fraction was collected by centrifugation (300g, 5 minutes), resuspended in fibroblast growth media, and plated on tissue-culture treated plastic, area ≈ 23 cm2 (0.5× 12-well plate) per LV, in a humidified tissue culture incubator. Media was changed after 24 hours and every 48 hours thereafter.

Osteocytes were isolated from mouse long bones utilizing a modified protocol derived from the combined methods of Gu et al. and Van Der Plas et al. (33 (link),44 (link),47 (link)). Long bones (femora, tibia, and humeri) were aseptically dissected from skeletally mature 4-month-old (young) and 22-month-old (old) C57BL/6 mice (Charles River Laboratories, Wilmington, MA, USA). The bones from young and old mice were processed separately by serial digestion as described in Table 1. The bones from each individual mouse were pooled together and treated as one sample. Collagenase solution was prepared as 300 active U/mL collagenase type-IA (Sigma-Aldrich, St. Louis, MO, USA) dissolved in α-minimal essential medium (αMEM; Mediatech, Manassas, VA, USA). EDTA tetrasodium salt dehydrate (EDTA) solution (5 mM, pH = 7.4; Sigma-Aldrich) was prepared in magnesium and calcium-free Dulbecco's phosphate-buffered solution (DPBS; Mediatech) with 1% BSA (Sigma-Aldrich). All steps of the digestion took place in 8 mL solution in a six-well Petri dish, on a rotating shaker set to 200 RPM, in a 37°C and 5% CO2 humidified incubator. Following each sequential digestion, the digest solution with suspended cells was removed from the bone pieces and kept. The bone pieces were then rinsed with Hank's balanced salt solution (HBSS) three times, and the rinsate was added to the digestion solution. The combined cell suspension solution was spun down at 200× g for 5 min, the supernatant was removed from the cell pellet, and cells were resuspended in culture medium and counted. The tissue homogenizer used in this study (Medimachine; BD Biosciences, San Jose, CA, USA) was utilized with a stainless steel mincing screen with a pore size of 50 μm.

Cell isolations were performed as previously described in mice [37 (link)] and modified slightly for rats [28 (link)]. Briefly, the gastrocnemius muscles from WB and HS male rats were excised and placed in muscle dissociation media (MDM) (Hams F-10 (Gibco, USA), 10% Horse Serum (Thermo Fisher), 1% penicillin/streptomycin (Gibco), 800 U/ml Collagenase II (Gibco)), and minced using sterilized surgical equipment. The muscle homogenate was then incubated in MDM for 1 h at 37 °C with gentle agitation. Following incubation, samples underwent further incubation in 1000 U/ml Collagenase II (Gibco) and 11 U/ml dispase (Gibco) for 30 min at 37 °C. The single-cell suspension was passed through an 18-gauge needle approximately 10 times prior to 0.2-μm filtration. Single cells were incubated in propidium iodide to identify dying/dead cells for removal via fluorescence-activated cell sorting (Sony Biotechnology, USA). Single-cell suspensions from each group were added to a Chromium Controller (10X Genomics, USA) using the Single Cell 3’ Reagent Kit per manufacturer’s instructions and sequenced on an Illumina HiSeq platform (Novogene, USA), yielding 200 million reads/sample.

The pancreases from P9-P10 pups were first perfused by 1 mg/ml collagenase in Hank’s balanced salt solution, dissected, and incubated at 37 °C for 10–12 min to release endocrine cells/islets. Digested pancreatic tissue was washed 3 × by 1% FBS in Hank’s solution. To generate single cells, the tissue was further dissociated by trypsinization as described [66 (link)]. Briefly, tissue was dissociated using 0.05% trypsin/0.53 mM EDTA at 37 °C for 5 min. Digestion was stopped by the FACS buffer (2% FBS and 10 mM EGTA in PBS [66 (link)]), and cells were then 1 × washed by FACS buffer. The pancreases microdissected from E14.5 embryos were directly trypsinized and prepared for FACS as described above. Finally, cell suspensions were filtered through 40 µm nylon mesh and immediately tdTomato+ cells were sorted using a flow cytometer (BD FACSAria™ Fusion), through a 100 µm nozzle in 20 psi, operated with BD FACSDiva™ Software (Additional file 1: Fig. S7). For RNA sequencing, 100 sorted cells were collected into individual wells of 96-well plate containing 5 µl of lysis buffer of NEB Next single-cell low input RNA library prep kit for Illumina (New England Biolabs #E6420). Plates were frozen immediately on dry ice and stored at − 80 °C. The total time from euthanasia to cell collection was ∼3 h. For the epigenetic study, on average, 4700 cells/sample at E14.5 and 14,700 cells/sample at P9 were sorted. Cell sorting was performed in the Imaging Methods Core Facility at BIOCEV.

HEK293T, MIA-PaCa-2, BxPC-3, and PANC-1 cell lines were obtained from the American Type Culture Collection (ATCC). They were cultured in Dulbecco’s modified Eagle’s medium (DMEM) supplemented with 10% fetal bovine serum (#S11150; FBS, Atlanta Biologicals), antibiotics (#P4458; Gibco) and L-glutamine (#17921004; Corning). The murine pancreatic cancer cell line KPC1 was originally described in our recent publication (Parajuli et al., 2018 (link)). The cell line was established from a KP53 mouse, which harbored KrasG12D and one conditional allele of Trp53 (LSL-KrasG12D;LSL-Trp53fl/+;Pdx1-Cre). Freshly isolated specimen from the KP53 mouse with terminal PDAC was gently dissected, minced with scissors, and digested with Dispase II at 2.4 U/ml (#4942078001; Sigma-Aldrich) and Collagenase D at 0.5 mg/ml (#11088858001; Sigma-Aldrich) for 1 h at 37°C in an atmosphere of 5% CO2. Then, cells were washed three times with PBS, suspended in RPMI 1540 containing 20% FCS, and seeded on fibronectin-coated plates. Cell colonies were subsequently passaged by trypsinization, pooled, and propagated in DMEM supplemented with 10% FBS, antibiotics, and L-glutamine. To generate the PANC-1-SMAD4KO and PANC-1-SMAD2/3KO cell lines, cells were transduced with the corresponding lentiCRISPRV2-gRNA lentiviruses, selected with puromycin (for SMAD4) or hygromycin (for SMAD2/3), and all resistant clones were pooled and expanded as a single population. Lentiviruses were produced by transfecting HEK293T cells with lentiviral constructs and the One-Step Lentivirus Packaging System as described by the manufacturer (#631275; Takara). Lentiviral particles in the conditioned media were harvested after a period of 48–72 h. The conditioned media were then cleaned of cell debris by centrifugation at 5,000×g for 15 min, filtered through a 0.45-μm filter, and used immediately for cell transduction.
