Age-dependent decrease in the chondrogenic potential of human bone marrow mesenchymal stromal cells expanded with fibroblast growth factor-2.

Background Aims: Human bone marrow mesenchymal stromal cells are useful in regenerative medicine for various diseases, but it remains unclear whether the aging of donors alters the multipotency of these cells. In this study, we examined age-related changes in the chondrogenic, osteogenic and adipogenic potential of mesenchymal stromal cells from 17 donors (25-81 years old), including patients with or without systemic vascular diseases.

Methods: All stem cell lines were expanded with fibroblast growth factor-2 and then exposed to differentiation induction media.

Human platelet lysate permits scale-up of dental pulp stromal cells for clinical applications.

BACKGROUND AIMS. Dental pulp stromal cells (DPSC) are considered to be a promising source of stem cells in the field of regenerative therapy. However, the usage of DPSC in transplantation requires large-scale expansion to cater for the need for clinical quantity without compromising current good manufacturing practice (cGMP).

Inherent differential propensity of dental pulp stem cells derived from human deciduous and permanent teeth.

Introduction: Lately, several new stem cell sources and their effective isolation have been reported that claim to have potential for therapeutic applications. However, it is not yet clear which type of stem cell sources are most potent and best for targeted therapy. Lack of understanding of nature of these cells and their lineage-specific propensity might hinder their full potential.

Micromanipulation of culture niche permits long-term expansion of dental pulp stem cells--an economic and commercial angle.

Stem cells isolated from dental pulp possess the capacity for self-renewal and the potential for multi-lineage differentiation. However, dental pulp stem cells have different characteristics in terms of their culture conditions. The success of stem cells culture is governed by its micro-environmental niche.
