Evaluation of Bone Marrow Processing Protocol for Therapeutic Applications via Culture and Characterization of Mesenchymal Stem Cells.

Introduction: Human mesenchymal stem cells from bone marrow (hMSCs) have broad therapeutic potential. These cells can be are readily isolated from bone marrow by their property to adhere to tissue culture treated culture wares. However, the proliferation rates and other properties of the cells gradually change during expansion. This study aims to validate the protocol of isolation and differentiation of hMSCs from bone marrow for therapeutic applications.

Methods: Sixty ml of bone marrow was extracted from 5 patients and MSCs were isolated. These were characterized by Flow Cytometry, CFU assay and were differentiated into bone, fat cells and neurocytes.

Results: The cells were having healthy morphology. These were positive for the markers CD105, CD90 and CD73 and negative for CD45, CD34 and HLA-DR. The cells could differentiate into fat, bone and neural cells.

Conclusion: MSCs from the bone marrow were isolated and differentiated. These cells were morphologically healthy and passed CFU assay. The cells exhibited differentiation potential into bone, fat and neural tissue. These cells can be used in therapeutic applications.
