Abstract

The study objectives include, enhancing the proliferations of aged bone marrow stem cells (BMSCs) and adipose stem cells (ADSCs); and evaluating the shelf lives of clinical grade chondrogenically induced cells from both samples. ADSCs and BMSCs from 56 patients (76 ± 8 yrs) were proliferated using basal medium (FD) and at (5, 10, 15, 20 and 25) ng/ml of basal fibroblast growth factor (bFGF). They were induced to chondrogenic lineage and stored for more than 120 hrs in FD, serum, Dulbecco's phosphate buffered saline (DPBS) and saline at 4°C. In FD, cells stagnated and BMSCs' population doubling time (PDT) was 137 ± 30 hrs, while ADSCs' was 129.7 ± 40 hrs. bFGF caused PDT's decrease to 24.5 ± 5.8 hrs in BMSCs and 22.0 ± 6.5 hrs in ADSCs (p = 0.0001). Both cells were positive to stem cell markers before inductions and thereafter, expressed significantly high chondrogenic genes (p = 0.0001). On shelf life, both cells maintained viabilities and counts above 70% in FD and serum after 120 hrs. BMSCs' viabilities in DPBS fell below 70% after 96 hrs and saline after 72 hrs. ADSCs' viability fell below 70% in DPBS after 24 hrs and saline within 24 hrs. Concentrations between 20 ng/ml bFGF is ideal for aged adult cells' proliferation and delivery time of induced BMSCs and ADSCs can be 120 hrs in 4°C serum.
