Research and Development

Besides manufacturing clinical grade stem cells, SBS pursues research and development in the domain of stem cells in order to create new cell therapy based modalities for human medical use. Adipose tissue derived stem cells (ADSCs) are self renewing cells that can differentiate to many other cell types. This makes ADSCs attractive starting material for developing cell based treatments for regenerative medicine applications. After transplantation the engrafted multipotent stem cells differentiate into different cell types and regenerate the damaged tissue. Alternatively, some secretomes of transplanted stem cells stimulates the endogenous stem cells that repair the damaged cells. This signaling from one cell to another is called the paracrine effect; the action of the secretion of one kind of cell on another kind. In fact paracrine effect acts by regenerating the damaged host tissue without direct engrafting of the the transplanted cells. Many different cell types, including adipose tissue derived stem cells, can invoke a paracrine response that result in activation of host stem cells after transplantation.

SBS’ research program is based on utilisation of the paracrine effect of stem cells. Our own experimental results and many other researchers’ show that paracrine effect is a major component of the regenerative effect of transplanted stem cells. Paracrine effect is exerted via secretomes of stem cells. A major component of the secretomes are Extracellular Vesicles (EVs).
