Abstract:

Objective

To find the difference between fibroblasts and umbilical cord mesemchemal stem cells (UCMSC) in surface markers and differentiation.

Methods

Flow cytometric analysis of CD105, CD90, CD73, CD44, CD14, CD34, CD45, CD79a, HLA-DR, FSP-1 and TM4SF1 was performed for fibroblasts and UCMSC. Multilineage differentiation of fibroblasts and UCMSC into fat cells, cartilage cells and bone cells were induced. The expression of FSP-1 and TM4SF1 in fibroblasts and in UCMSC was assayed by RT-PCR. Data analysis between different groups was perfermed with independent-sample t test.

Results

Those markers which were found to be expressed on UCMSC were also expressed on fibroblasts in comparable levels (P > 0.05). Fibroblasts and UCMSC could differentiate into fat cells, cartilage cells and bone cells in vitro. Both fibroblasts and UCMSC were positive for FSP-1 (98.6±0.3323)﹪ vs (98.90±0.2665)﹪, (t?=?0.4677, P?=?0.5294). TM4SF1 was positive on UCMSC (97.23±0.2250)﹪, but negative on fibroblast (0.0082±0.0018)﹪(t?=?346.9, P?<?0.01).

Conclusion

There is a significant difference in expression of TM4SF1 between fibroblasts and UCMSC.
