New light shed on how bone marrow niches keep stem cells thriving

Japanese researchers uncover cellular factor needed to maintain the environment that regulates hematopoietic stem cell Osaka – Hematopoietic stem cells (HSCs) are a class of stem cells located in bone marrow. HSCs give rise to every type of blood cell–from the red blood cells that carry oxygen to the white blood cells of the immune […]

Transplantation of Hepatocyte Growth Factor–Modified Dental Pulp Stem Cells Prevents Bone Loss in the Early Phase of Ovariectomy-Induced Osteoporosis

Abstract Investigations based on mesenchymal stem cells (MSCs) for osteoporosis have attracted attention recently. MSCs can be derived from various tissues, such as bone marrow, adipose, umbilical cord, placenta, and dental pulp. Among these, dental pulp–derived MSCs (DPSCs) and hepatocyte growth factor (HGF)-modified DPSCs (DPSCs-HGF) highly express osteogenic-related genes and have stronger osteogenic differentiation capacities. […]

Dentists Find Tooth Root Pulp Can Become an Alternative Source of Stem Cells

WISDOM IN TEETH A collaboration of dentists and engineers from the University of Nevada, Las Vegas (UNLV) made a discovery that could potentially revolutionize how and where we harvest, preserve, and use stem cells. In a study published in Biomaterials and Biomechanics in Bioengineering, the team led by UNLV biomedical sciences professor Karl Kingsley and […]
