Role Of Dpy30 In The Epigenetic Regulation Of Odontoblast Differentiation In Vitro, Namrate Landge Rana
Role Of Dpy30 In The Epigenetic Regulation Of Odontoblast Differentiation In Vitro, Namrate Landge Rana
All ETDs from UAB
Purpose: Dentin is produced from odontoblasts, derived from human Dental Pulp Cells (hDPCs), which are essential for dentin formation, remodeling, and mineral hemostasis. Epigenetic mechanisms are believed to be involved in odontoblast differentiation and function, and H3K4 methylation is associated with gene activation which is fundamental to histone-based epigenetics. The SET1/MLL complexes are mammals' major histone H3K4 methylation enzymes. DPY30 is a core subunit of SET1/MII complexes, mammalian's major histone H3K4 methyltransferases. It plays an important role in regulating fundamental processes including the determination of cell lineage, growth, and differentiation. Thus, histone-based epigenetic mechanisms are involved in odontoblast differentiation and …
Stem Cell Therapy For Insulin-Dependent Diabetes: Are We Still On The Road?, Lu Yang, Zhu-Meng Hu, Fang-Xu Jiang, Wei Wang
Stem Cell Therapy For Insulin-Dependent Diabetes: Are We Still On The Road?, Lu Yang, Zhu-Meng Hu, Fang-Xu Jiang, Wei Wang
Research outputs 2022 to 2026
In insulin-dependent diabetes, the islet β cells do not produce enough insulin and the patients must receive exogenous insulin to control blood sugar. However, there are still many deficiencies in exogenous insulin supplementation. Therefore, the replacement of destroyed functional β cells with insulin-secreting cells derived from functional stem cells is a good idea as a new therapeutic idea. This review introduces the development schedule of mouse and human embryonic islets. The differences between mouse and human pancreas embryo development were also listed. Accordingly to the different sources of stem cells, the important research achievements on the differentiation of insulin-secreting β …

Introduction: Many studies in stem cell biology have demonstrated that dental pulp stem cells (DPSC) may be highly proliferative and capable of pluripotent differentiation into many different tissue types. Recent advances in stem cell research have outlined methods for directing in vitro or in vivo growth, viability, and proliferation, as well as differentiation of DPSC-although much remains to be discovered. Based upon this information, the primary objective of this study was to understand the functional biomaterials needed to more effectively direct DPSC viability, growth, and proliferation. Methods: Using an approved protocol, previously collected and isolated samples of DPSC from an …

Phenotypic Characterization And Differentiation Of Mesenchymal Stem Cells Originating From Adipose Tissue, Ece Çerçi̇, Hati̇ce Erdost
Turkish Journal of Veterinary & Animal Sciences
Stem cells are known as undifferentiated cells that are capable of divisions and self-renewal over an extended period. Adipose tissue-derived mesenchymal stem cells (ADSCs) are known to differentiate into many different organ and tissue cells. The purpose of this study was to characterize adipose tissue-derived mesenchymal stem cells in detail based on the expression status of certain surface markers and differentiation stages for clinical and laboratory applications. The migrating phase and mitotic property of the cells from adipose tissue were assessed under a microscope. Cell counting was performed during the first, second, and third passages. The cells were differentiated into …

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 …

Previous studies reported that embryonic stem cells (ESCs) can be induced to differentiate into cells showing a mature osteoblastic phenotype by culturing them under osteo-inductive conditions. It is probable that osteogenic differentiation requires that ESCs undergo differentiation through an intermediary step involving a mesenchymal lineage precursor. Based on our previous studies indicating that adult mesenchymal progenitor cells express αSMA, we have generated ESCs from transgenic mice in which an αSMA promoter directs the expression of red fluorescent protein (RFP) to mesenchymal progenitor cells. To track the transition of ESC-derived MSCs into mature osteoblasts, we have utilized a bone-specific fragment of …
Identification Of Genes Responsible For Maintenance Of Differentiation Capability In Dental Pulp Stem Cells, Michael B. Flanagan
Identification Of Genes Responsible For Maintenance Of Differentiation Capability In Dental Pulp Stem Cells, Michael B. Flanagan
LSU Doctoral Dissertations
Stem cells exist in various tissues, including dental follicles and dental pulps. Adult stem cells (ASC) can be isolated from patients for autologous transplantation, which eliminates the risk of immune rejection with low or no tumorigenesis. However, one of the challenges is that ASC progressively lose their differentiation ability when cultured in vitro. This prevents expansion of large quantities of high-potential stem cells for therapeutics, especially for stem cells with limited tissue source, such as dental pulp stem cells (DPSC). The goal of this study is to define possible molecular regulation causing loss of differentiation. To achieve this goal, we …

Keratocan is an extracellular matrix protein that belongs to the small leucine-rich proteoglycan family which also includes the lumican, biglycan, decorin, mimecan and fibromodulin. Members of this family are known to play a role in regulating cellular processes such as proliferation and modulation of osteoprogenitor lineage differentiation. The aims of this study were to evaluate the expression pattern of the keratocan within the osteoprogenitor lineage and assess its role in regulating osteoblast maturation and function. Results from gene expression analyses of cells at different maturation stages within the osteoblast lineage indicate that keratocan is differentially expressed by osteoblasts and shows …
