Expansion of CD133+ Umbilical Cord Blood Derived Hematopoietic Stem Cells on a Biocompatible Microwells

چکیده
Umbilical cord Blood (UCB) as a source of Hematopoietic Stem/Progenitor cells (HSPCs) used for Umbilical cord blood transplantation (UCBT). The main obstacle in application of this source as an appropriate source of HSPCs is low volume of this product. So ex vivo expansion of these cells in a microenvironment which mimic body condition is important. In current study we designed biocompatible microwells in which collagene type I is coated by softlitography method. Our findings designated that in 3-Dimensional (3D) microenvironment CD133(+) UCB derived HSC expanded significantly compared to 2-Dimensional (2D) microenvironment.

Background and purpose: Umbilical cord blood (UCB) is a source of Hematopoietic stem cells (HSCs) and has received a lot of attention due to its availability, renewal capacity, proliferation rate, and differentiation potential. The main limitation of using these cells is their low quantity in one unite of UCB. To overcome this, HSCs co-culturing with UCB derived mesenchymal cells (MSCs) is a pr...

Background and Objective: Nowadays, although umbilical cord blood is a commonly used source of hematopoietic stem cell, its low frequency of these cells is the main factor limiting its clinical application. The transplantation of hematopoietic stem cells derived from placenta tissue along with umbilical cord blood cells of the same sample may be an appropriate approach to solve this problem. In...
