Experimental in vitro modeling of hematopoiesis by using diffusion chambers of an original design

One of the most important tasks biotechnology and regenerative medicine is to achieve long-term expansion hematopoietic stem cells. promising approaches optimizing cultures cells creation a microenvironment in form feeder stromal layers, which allows for reproduction combination soluble cytokines growth factors necessary hematopoiesis promotes an increase their proliferation [1,2].
