Mouse recombinant noggin

Manufactured by Thermo Fisher Scientific
Sourced in United States, Switzerland

Thermo Fisher Scientific's Mouse Recombinant Noggin is a purified protein that functions as a bone morphogenetic protein (BMP) antagonist. Noggin binds to and inhibits the activity of various BMPs, thereby regulating developmental processes such as embryonic patterning, skeletal morphogenesis, and neural induction.

SI organoids were derived from Hvem/− or littermate Hvem+/+ mice. The proximal SI was cut into 5-mm segments and incubated in 4°C 2 mM EDTA in PBS for 5 min and washed by pipetting. The segments were incubated in 2 mM EDTA in PBS for 30 min at 4°C, and crypts were isolated by pipetting with cold HBSS. Dissociated crypts were passed through a 70-μm cell strainer and pelleted by centrifuge at 600 rpm for 3 min at 4°C. The crypts were resuspended in Advanced DMEM/F12 medium (Thermo Fisher Scientific); the number of crypts was counted, and they were resuspended in Matrigel Growth Factor Reduced (GFR) Basement Membrane Matrix (Corning). The crypts were plated in a 24-well plate with organoid growth medium supplemented with 100 μg/ml penicillin, 100 U/ml streptomycin, 2 mM Glutamax, 1×N-2 supplement, 1×B27 supplement, 10 mM HEPES (Thermo Fisher Scientific), 1 mM N-acetylcysteine (Sigma-Aldrich), 100 ng/ml recombinant mouse Noggin (Peprotech), 50 ng/ml recombinant mouse EGF (BioLegend), 500 ng/ml recombinant human R-spondin 1 (Peprotech).

For maintenance of the ABCG2-positive population, CnT-30 was replaced with CnT-07 (CELLnTEC Advanced Cell Systems AG, Bern, Switzerland) supplemented with ENRC (50 ng/ml mouse recombinant epidermal growth factor (EGF, Invitrogen), 100 ng/ml mouse recombinant Noggin, 1 μg/ml human recombinant R-spondin (both from PeproTech), and 3 μM CHIR-99021 (Stemgent)) at d10–11 of the standard CnT-30 differentiation protocol. New medium was introduced directly to the adherent cultures; alternatively, the hPSC-LSCs were concomitantly passaged onto fresh LN-521/Col IV-coated wells at a density of 1 000 cells/cm2 in the new medium. The cells were thereafter cultured following the standard feeding regimen. After the emergence of ABCG2-positive colonies in approximately 7–10 days, further expansion of the ABCG2-positive hPSC-LSCs in the ENRC medium was carried out by passaging subconfluent cultures onto fresh LN-521/Col IV-coated matrices at a density of 1 000 cells/cm2. Batches of the passaged cells were also cryopreserved following our routine cryopreservation protocol [24 (link), 25 ]. Throughout the article, the term “ENRC maintenance condition” refers to the novel CnT-07-based, ENRC-supplemented culture protocol described in this chapter.

Mouse lungs were removed, flushed, cut into 5-mm3 pieces and incubated with digestion buffer containing 1.0 mg ml−1 collagenase I (Gibco, 17100–017) and 0.5 mg ml−1 collagenase IV (Gibco, 17104–019) in DMEM/F12 (Gibco, C11330500BT) in gentleMACS C tubes (Miltenyi Biotec, 130-096-334). After dissociation by the gentleMACS dissociator, samples were filtered through 70-μm filters, collected by centrifugation and resuspended in ice-cold Matrigel (BD, 354230) at a ratio of 1:20 (vol:vol). The basic culture medium for mouse lung organoids was slightly modified from a previous report43 (link), where DMEM/F12 was supplemented with penicillin/streptomycin (Gibco, 15140–122), 2 mM GlutaMAX (Peprotech, 35050–061), 1× B27 (Gibco, A3582801), 1× N2 (Gibco, 17502048), 10 nM gastrin I (Peprotech, 1003377), 1 mM N-acetylcysteine (Sigma, A9165) and 10 mM nicotinamide (Sigma, N0636). The following growth factors were used: 50 ng ml−1 mouse recombinant epidermal growth factor (Peprotech, AF-100-15-1000), 100 ng ml−1 mouse recombinant noggin (Peprotech, 120-10C-250), 500 ng ml−1 mouse recombinant FGF10 (Peprotech, 100-26-1000), 125 ng ml−1 R-spondin-1 (Peprotech, 120-38-1000), 10% Wnt-3A conditioned medium and 500 nM A83–01 (Peprotech, 9094360). The medium was changed every 3 d. Organoids were passaged by mechanical dissociation in TrypLE (Gibco, 12605–028) every 5–7 d.

For organoid experiments, normal colon organoids with genetic engineering of TP53 KO and RB1 KO, and gastric organoids with TP53 KO were used in this experiment as previously reported (16 (link)). Culture conditions were as previously described, with Advanced Dulbecco's Modified Eagle Medium/F12 supplemented with penicillin/streptomycin, 10 mmol/L HEPES, 2 mmol/L Gluta-MAX, 1 × B27 (Thermo Fisher Scientific), 10 nmol/L gastrin I (MilliporeSigma), and 1 mmol/L N-acetylcysteine (FUJIFILM Wako Pure Chemical Corporation). Complete medium was prepared by supplementing the basal culture medium with the following niche factors: 50 ng/mL mouse recombinant EGF (Thermo Fisher Scientific), 50 ng/mL human recombinant FGF2 (PeproTech), 100 ng/mL human recombinant IGF1 (BioLegend), 100 ng/mL mouse recombinant noggin (PeproTech), 1 μg/mL recombinant human R-spondin-1 (Bio-Techne), 25% Afamin-Wnt-3A serum-free conditioned medium, and 500 nmol/L A83-01 (Tocris Bioscience). For organoid experiments, N-[N-(3,5-difluorophenacetyl)-1-alanyl]-S-phenylglycine t-butyl ester (DAPT; MilliporeSigma, 10 μmol/L) was added on day 1. EGF/FGF2/IGF1 were removed from the culture media on day 5, and the organoids were collected on day 10, fixed with 4% paraformaldehyde, and immunostained using mouse antisynaptophysin.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
