ABSTRACT
BACKGROUND:
Stem cells from human exfoliated deciduous teeth (SHED) are regarded as an attractive cell source for tissue regeneration. However, the effect of different levels of root resorption on the characteristics of SHED remains less understood. Thus, the tooth source that is most suitable for the isolation of SHEDs needs to be determined. To compare cellular and biological characteristics of stem cells from human exfoliated deciduous posterior teeth with varying levels of root resorption.METHODS:
The pulp was obtained from the deciduous posterior teeth depending on the level of root resorption, and isolated SHEDs were grouped as follows Teeth with 0 to 1/3rd root resorption as SHEDs (G1) and 1/3rd to 2/3rd root resorption as SHEDs (G2). Teeth were also collected from >2/3rd root resorption status, but failed to establish primary culture of SHED as the availability of pulp tissue was too less. Later, isolated SHEDs were compared on their morphology, viability, growth kinetics, colony-forming ability, expression of cell surface markers and in vitro differentiation into osteocytes and adipocytes.RESULTS:
No major differences were observed in terms of cellular morphology, viability, proliferation rate, colony-forming ability, cell surface markers expression, and mesenchymal lineage differentiation of SHEDs isolated from posterior teeth with 0 to 1/3rd and 1/3rd to 2/3rd root resorption. However, SHED from teeth with 0 to 1/3rd root resorption (G1) displayed relatively higher proliferation capacity and expression of selected markers.CONCLUSIONS:
Collectively, SHEDs (G1) and SHEDs (G2) showed comparable cellular and biological characteristics that enable their possible applications in regenerative therapies.
