Embodiment 1

[0028] Example 1 Formula screening of mesenchymal stem cell adipogenic differentiation medium

[0029] The inventors conducted experimental screening on the adipogenic induction differentiation medium of mesenchymal stem cells. Take P3 generation bone marrow mesenchymal stem cells at 5000 cells / cm 2 The density of the cells was inoculated in a six-well plate, and cultured with DMEM / F12 medium containing 10% (v / v) FBS. When the confluence of the cells reached 80%, the medium was discarded, and induction medium 1 and induction medium 1 were added respectively. Medium 3, the medium was changed every 3 days. After induction and culture for 3 weeks, the expression level of the adipogenic cell-related gene FABP4 was identified by qPCR, and the results were as follows: figure 1 shown.

[0030] from figure 1 It can be seen that adding a certain concentration of Fasudil hydrochloride to the adipogenic induction and differentiation medium of mesenchymal stem cells in the prior art...

Embodiment 2

[0032] Example 2 Mesenchymal stem cell adipogenic induction differentiation medium

[0033] Mesenchymal stem cell adipogenic differentiation medium, including DMEM / F12 medium, also includes the following components and their concentrations: FBS 10% by volume, glutamine 1% by volume, penicillin-streptomycin 1% by volume , indomethacin 200 μM, insulin 100 nM, dexamethasone 10 nM, 3-isobutyl-1-methylxanthine 1 μM and fasudil hydrochloride 0.1 μM.

[0034] Preparation method: Add FBS, glutamine, antibiotics, indomethacin mother solution, insulin mother solution, dexamethasone mother solution, 3-isobutyl-1-methylxanthine to the DMEM / F12 medium according to the stated concentration The mother liquor and the fasudil hydrochloride mother liquor are stirred evenly, and the bacteria are passed through a membrane to remove bacteria.

[0035]Preparation of indomethacin mother solution: take 100mg, dissolve in 50% methanol, make 20mM mother solution, and store at -20°C. Preparation of ...

Embodiment 3

[0036] Example 3 Mesenchymal Stem Cell Adipogenic Induction Differentiation Medium

[0037] Mesenchymal stem cell adipogenic differentiation medium, including DMEM / F12 medium, also includes the following components and their concentrations: FBS 15% by volume, glutamine 1% by volume, antibiotics 1% by volume, indomethacin Dixime 150 μM, insulin 50 nM, dexamethasone 10 nM, 3-isobutyl-1-methylxanthine 2 μM and fasudil hydrochloride 0.2 μM.

[0038] Preparation method: similar to the preparation method in Example 2.

Abstract

The present invention provides a mesenchymal stem cell adipogenic differentiation culture medium, and belongs to the technical field of stem cells. The mesenchymal stem cell adipogenic differentiation culture medium comprises a DMEM/F12 culture medium, and further comprises FBS with a volume percentage of 5-50%, glutamine with a volume percentage of 0.5-5%, antibiotic with a volume percentage of 0.5-5%, 50-500 [mu]M indometacin, 50-500 nM insulin, 5-50 nM dexamethasone, 0.5-5 [mu]M 3-isobutyl-1-methylxanthine, and 0.05-0.5 [mu]M fasudil hydrochloride. The mesenchymal stem cell adipogenic differentiation culture medium of the present invention has advantages of high inducing efficiency and the like.

Description

technical field [0001] The invention belongs to the technical field of stem cells, and relates to a mesenchymal stem cell adipogenic differentiation medium and a preparation method thereof. Background technique [0002] Mesenchymal stem cells (MSCs) are a type of adult stem cells with obvious plasticity and multi-directional differentiation potential. Under the regulation of different growth factors, they can differentiate into different tissue cell types derived from the three germ layers, such as fat cells, osteoblasts, liver-like cells, cardiomyocyte-like cells, glial cells, neuron cells and islet-like cells, etc. In addition, human mesenchymal stem cells do not express major histocompatibility class II antigens, but express a small amount of major histocompatibility class I antigens, have low immunogenicity, have little transplant rejection, and have immunoregulatory effects. Human amniotic membrane after transplantation The nutritional factors secreted by mesenchymal s...
