The Effects Of Cryopreservation On Human Dental Pulp-Derived Mesenchymal Stem Cells, Allison Elaine Tomlin Dec 2016

The Effects Of Cryopreservation On Human Dental Pulp-Derived Mesenchymal Stem Cells, Allison Elaine Tomlin

UNLV Theses, Dissertations, Professional Papers, and Capstones

Many studies have demonstrated clinical applications for the use of dental pulp stem cells (DPSC) for the treatment of various conditions. This has driven medical and scientific interest in the collection, isolation and banking of DPSC tissues for research into these potential therapies. Few studies to date have evaluated the viability of DPSC following long-term cryopreservation. The purpose of this study is to evaluate the effects of cryopreservation on dental pulp-derived stem cells (DPSC) viability over a period of three years. Dental pulp-derived stem cells were isolated and cultured from thirty-one healthy teeth. DPSC isolates were assessed for doubling-time and …

Introduction

Mesenchymal stem cell (MSC) research is a contemporary topic in modern healthcare. These cells have the ability to divide and generate progeny, which then become committed to specific and distinctive end-stage phenotypes, such as cartilage or bone (Caplan 1991). MSCs have been isolated from a variety of tissues such as the umbilical cord, bone marrow, adipose tissue (Ding, Shyu & Lin 2011) and dental pulp (Takeda et al 2008). Although dental pulp is a viable source for MSCs, peer reviewed research has given limited attention to its retrieval process through intentional tooth splitting of extracted teeth. The purpose of …


Induction Of Differentiation Of Dental Pulp-Derived Mesenchymal Stem Cells (Dpsc), Aubrey Young Dec 2014

Induction Of Differentiation Of Dental Pulp-Derived Mesenchymal Stem Cells (Dpsc), Aubrey Young

UNLV Theses, Dissertations, Professional Papers, and Capstones

Mesenchymal stem cells are derived from a variety of human tissues and are being bioengineered and studied for possible uses in the advancement of medicine. Recent efforts are being focused on Dental Pulp Stem Cells (DPSC's) due to the accessibility of this tissue. Many factors influence DPSC quality and quantity, including the specific methods used to isolate, collect, concentrate, and store these isolates once they are removed. Ancillary factors, such as the choice of media, the selection of early versus late passage cells, and cryopreservation techniques may also influence the differentiation potential and proliferative capacity of DPSC isolates.

The objective …


Adult Permanent (Extracted) Teeth As A Source Of Dental Pulp-Derived Mesenchymal Stem Cells (Dpsc): A Pilot Study, Charles Hill Aug 2013

Adult Permanent (Extracted) Teeth As A Source Of Dental Pulp-Derived Mesenchymal Stem Cells (Dpsc): A Pilot Study, Charles Hill

UNLV Theses, Dissertations, Professional Papers, and Capstones

Mesenchymal stem cells (MSC) may be derived from a variety of adult human tissues, including dental pulp from extracted or exfoliated teeth. Evidence suggests differences in both the quality and quantity of the dental pulp-derived mesenchymal stem cells (DPSC) obtained from different sources, such as primary or "baby teeth" and adult, permanent teeth. This study aimed to evaluate the potential to obtain DPSC from intact, vital permanent teeth, and characterize the potential isolates using a randomized selection of active dental patients from the University of Nevada, Las Vegas School of Dental Medicine (UNLVSODM). DPSC were extracted, isolated, cultured and characterized …
