ABSTRACT

Objective To investigate the growth and exocrine function of BM-MSC derived from PBC patients.Methods To compare the growth patterns and cytokines secretions between PBC patients and healthy controls by student's t test.Results ① There was no difference in growth profile and speed between PBC patients and healthy controls.② The level of TGF-β1 was much lower in the supernatant of BM-MS from OBC patients than health controls [(2.6±1.9)vs (8.2±6.7)ng/ml,t=-3.641,P=0.001].There were no other differences between two groups' BM-MSC.③ The super natant concentration of interlukin-10 of the third BM-MSC subculture from healthy controls was lower than that of the primary subculture [(18.5±5.0) vs (12.4±3.1) pg/ml,t=2.368,P=0.045],and that of hepatic growth factor from the second subcuhure was higher than the primary subculture [(0.21±0.07) vs (0.35±0.08) ng/ml,t=-2.874,P=0.021].There were seldom discrepancies in other cytokines between different generations of BM-MSC.Conclusion BM-MSC from PBC patients may have almost the similar characters in growth pattern and cytokines secretion as,except the TGF-β1,which was much lower than those from healthy controls.The second subculture of BM-MSC might be more suitable for the treatment to patients with PBC.
