Abstract

To study the feasibility of isolation and culture of adipose-derived stem cells( ADSCs) from SD rat adipose tissues subjected to long-term cryopreservation. We took inguinal fat pads from healthy SD rats. Adipose tissues were stored with 100 m L / L dimethyl sulfoxide( DMSO) combined with 900 m L / L fetal bovine serum( FBS) in liquid nitrogen. Three months later,the adipose tissues were resuscitated for the isolation and culture of ADSCs. The growth status and morphology were observed. The growth curve and cell surface markers CD29,CD45,CD90 of the 3rd passage cells were analyzed respectively by CCK-8 assay and immunocytochemistry. The 3rd passage cells were induced towards adipogenic lineages and osteogenic lineages by different inducers,and the resulting cells were examined separately by oil red O staining and alizarin red staining. The ADSCs obtained from SD rat adipose tissues subjected to long-term cryopreservation showed a spindle-shape appearance and had a good proliferation ability. The cell growth curve was typical "S " curve.Immunocytochemistry showed that the 3rd passage cells were positive for CD29 and CD90,while negative for CD45. The cells were positive for oil red O staining after adipogenic induction,and also p...Continue Reading

Adult Stem Cells

Adult stem cells reside in unique niches that provide vital cues for their survival, self-renewal, and differentiation. They hold great promise for use in tissue repair and regeneration as a novel therapeutic strategies. Here is the latest research.
