Isolation of Human Mesenchymal Stem Cells and their Cultivation on the Porous Bone Matrix
February 9th, 2015
Mesenchymal stem cells (MSCs) have a differentiation potential towards osteoblastic lineage when they are stimulated with soluble factors or specific biomaterials. This work presents a novel option for the delivery of MSCs from human amniotic membrane (AM-hMSCs) that employs the bovine bone matrix Nukbone (NKB) as a scaffold.
Overview
This study explores the culture of human mesenchymal stem cells (MSCs) on a porous bovine bone matrix, aiming to enhance their delivery for bone injury therapies. The method involves isolating MSCs from human amniotic membrane and utilizing a bovine bone matrix scaffold to support cell growth and proliferation.
