Regenerative Potential of Stem Cells Derived from Human Exfoliated Deciduous (SHED) Teeth during Engineering of Human Body Tissues.

Abstract

The current decade witnesses the regenerative potential of Stem Cells (SCs) based lifesaving therapies for the treatment of various disease conditions. Human teeth act as a reservoir for SCs that exist in high abundance in baby, wisdom, and permanent teeth. The collection of Stem cells from Human Exfoliated Deciduous teeth (SHED) is considered a simple process as it offers the convenience of little or no pain. In comparison to the SCs from dental or bone marrow or other tissues, the SHED offers the benefit of higher cellular differentiation and proliferation. Massive in vitro and in vivo studies reveal the regenerative potential of SHED in the engineering of the dental pulp tissue, neuronal tissue, root, bio root, cardiovascular tissues, lymphatic tissues, renal tissues, dermal tissues, hepatic tissues, and bone tissues. The current review describes the methods of collection/ isolation/storage, various biomarkers, and types of SHED. This review highlights the regenerative potential of SHED in the engineering of different tissues of the human body. As per the available research evidence, the present study supports that SHED may differentiate into the endothelial cells, neurons, odontoblasts, pancreatic β-cells, hepatocytes, renal cells, fibroblasts, osteoblasts, and many other types of cells. The present study recommends that further clinical trials are required before the clinical application of SHED-based therapies.
