Mesenchymal stem cells from bone marrow of patients with drug-resistant tuberculosis for cellular therapy

Abstract

In this study, we evaluated the proliferative capacity of mesenchymal stem cells (MSCs) from the bone marrow of patients with drug-resistant tuberculosis (DR-TB) and selected the optimal conditions for obtaining autologous MSCs transplant. The results of the expansion of MSCs from 42 patients with DR-TB in medium with 10% FBS demonstrated low proliferative potential for of these cells compared with MSCs from 47 donors. MSCs content in 1 ml of bone marrow of patients was also lower. A relationship was found between the amount of MSCs in the primary culture and in the finished product, and with a small number of cells in the primary culture, we used 5% platelet lysate instead of 10% FTS, which made it possible to obtain a high dose of MSCs in the transplant.
