Introduction
here are several differences between primary teeth and permanent
teeth in terms of their evolution process, tissue architecture and
their function. Stem Cells from Human Exfoliated Deciduous
Teeth (SHED) have greater proliferative power in comparison to
dental pulp stem cell (DPSC). Besides, these primary teeth are
much smaller in size and much brighter than permanent ones.
they have short Bulbaceous crown, tight Cervical canal, small
rodent, narrow root, thin dentin and enamel thickness; with much
wider teeth marrow which make them superior to permanent
teeth. it has been shown that primary dental pulp contain stem
cells which can be used as cell resource for therapeutic applica-
tions like umbilical cord stem cells. To engineer tissues in vitro, the
irst step is to isolate cells with the right phenotype and propagate
them in suitable culturing environments. Normally, dental pulp
stem cells are grown on a two-dimensional surface before being
transferred to a three-dimensional scaffold construct. There was
no report to our knowledge about the derivation of DPSCs from
the other tooth types. The incidence of supernumerary teeth var-
ies depending on the literature source. Here, we presented our re-
cent success in the isolation and characterization of DPSCs from
the pulp tissue of a supernumerary tooth.
Materials and Methods
Primary teeth falling and their replacement with permanent ones,
is physiologically an active process which involves the genesis of
permanent teeth and the absorption of primary teeth roots si-
Abstract
Objective: in this study we tried to isolated stem cells from human primary dental pulp. These cells are capable of differentiating into
a variety of cell types including neural cells, adipocytes, and odontoblasts, osteoblast
Background & Aim: Among different source for stem cells, less attention has been paid to the human dental pulp. Human dental
pulps are the best and new source for stem cells, and have potential to different to all kinds of cells. So the aim of this study was to
evaluate the pulp ability for produce stem cells.
Materials and Methods: Normal exfoliated human deciduous incisors collected from6- to 12-years-old children. The pulp was sepa-
rated from the crown and digested with trypsin .stem cells cultured in DMEM(Dulbecco’s Modiied Eagle’s Medium), supplemented
with 20% fetal bovine serum in a 37°C incubator with 5% co
2
. The cells were differentiated into the osteoblastic and adipocytic lineages
in different subcultures
Results: Stem cells are able to growth and proliferate unlimitedly and differentiate to all kinds of the cells in human body. Their life
time is very long and they remain their potential for long periods of time. For this reasons today many physicians and researchers
consider them as a therapeutic agent to cure diseases. One of the most important advantaged of dental pulp stem cells, is that isolated
from primary dental, that are thrown away usually. Various scaffolds have been used to cell culture. Stem cells were observed to grow
in colony forming units, mainly composed of a ibroblast-like cell population.
Conclusion: This study show that pulp contains cells with high proliferation capacity. The cells can be used for clinical application.
Cells can be considered as an easy accessible source of mesenchymal stem cells for stem cell research and tissue engineering.
