What are Progenitor Cells

April 18, 2012

A progenitor cell is similar to a stem cell in that it has the ability to differentiate into a specific type of cell.   The progenitor cell is already more specific than a stem cell and is pushed to differentiate into its “target” cell. The most important difference between stem cells and progenitor cells is that stem cells [...]

Mesenchymal Stem Cells from Umbilical Cord Tissue

August 16, 2011

Mesenchymal stem cells (MSCs) have the capability for renewal and differentiation into various lineages of mesenchymal tissues. These features of MSCs attract a lot of attention from investigators in the context of cell-based therapies of several human diseases. Despite the fact that bone marrow represents the main available source of MSCs, the use of bone [...]

Cord blood cells accelerate diabetic wound healing

February 23, 2011

Washington, Feb 23 (ANI): Korean scientists have found that transplanting human umbilical cord blood-derived endothelial progenitor cells (EPCs) ‘significantly accelerate’ wound closure in diabetic mouse models. Diabetes is often associated with impaired wound healing, according to study’s corresponding author, Wonhee Suh of the CHA University Stem Cell Institute. “EPCs are involved in revascularization of injured [...]

Expansion of Functional Human Natural Killer Cells from Umbilical Cord Blood CD34-Positive Cells for Adoptive Cancer Immunotherapy

January 25, 2011

Immunotherapy based on natural killer (NK) cell infusions is a potential adjuvant treatment for many cancers. Such therapeutic application in humans requires large numbers of functional NK cells that have been selected and expanded using clinical grade protocols. We established an extremely efficient cytokine-based culture system for ex vivo expansion of NK cells from hematopoietic [...]

Factors Influencing Cord Blood Viability, a new study

April 14, 2010

Cord blood (CB) viability determines stem cell quality and varies with time and temperature of exposure prior to cryopreservation. In a recent study published in Transfusion – The Journal of AABB (Vol. 50, Issue 4) researchers from the Departments of Pathology and Pediatrics, St Louis University School of Medicine ; and St Louis Cord Blood Bank [...]
