A Cytocentric Giant: Hal Broxmeyer
In December, we lost a mighty scientist who founded modern cord blood medicine, and showed the whole world how constant physiologic oxygen is critical to cells during isolation.
Oxygen Intrinsically Linked to Cell Senescence
Wiley and Campisi delve into the myriad causes of cellular senescence, including the influence of oxygen on senescent cell phenotype and frequency.
MSC Therapy is Improved by Physiologic O2
A comprehensive review by Egger et al. concludes that physiologic O2 levels maintain or increase the therapeutic properties of MSCs, and calls for reduced oxygen conditions during isolation and expansion of cells for cell products.
