Bmp Regulation Of Cyst Stem Cell Division In The Drosophila Testis Stem Cell Niche, Mohamoud Ahmed
Bmp Regulation Of Cyst Stem Cell Division In The Drosophila Testis Stem Cell Niche, Mohamoud Ahmed
Ursidae: The Undergraduate Research Journal at the University of Northern Colorado
Adult stem cells are found throughout the body and divide to replace dead cells or regenerate damaged tissues. We study the Drosophila melanogaster (fruit fly) testis as a model to investigate how adult stem cells are maintained by the intricate microenvironments in which they live, called stem cell niches. Many basic characteristics of adult stem cells in higher organisms were first discovered in the simple stem cell niches found in Drosophila. The testis niche is comprised of two distinct stem cells called germline stem cells (GSCs) and cyst stem cells (CySCs). This niche also contains a structure called the hub …

On December 18, 2015, President Obama signed into law a policy rider forestalling the therapeutic modification of the human germ line. The rider, motivated by the science’s potential unethical ends, is only the most recent instance in which the legislature cut short the ongoing national conversation on the acceptability of a developing science. This essay offers historical perspective on what bills were proposed and passed surrounding four other then-developing scientific breakthroughs—Recombinant DNA, in vitro fertilization, Cloning, Stem Cells—to better analyze how Congress is, and should, regulate this exciting and promising science.
Induction Of Differentiation Of Dental Pulp-Derived Mesenchymal Stem Cells (Dpsc), Aubrey Young
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.

Stem Cells As A Cure For Amyotrophic Lateral Sclerosis, Chaya K. Hirsch
Stem Cells As A Cure For Amyotrophic Lateral Sclerosis, Chaya K. Hirsch
The Science Journal of the Lander College of Arts and Sciences
Amyotrophic Lateral Sclerosis (ALS) is a fatal motor neuron disease which affects approximately 30,000 Americans at any given time (alsa.org, 2010). The etiology of this terminal disease unfortunately remains an unsolved mystery and has therefore severely limited the ability to find a cure. The use of stem cells to regenerate neurons has been vastly studied and have produced very promising results. However, its practicality as a cure or treatment for neurodegenerative diseases, such as ALS, is greatly compromised. Three different therapies involving stem cells were examined, Embryonic Stem Cells (ESC), induced pluripotent stem cells, (iPSC) and direct reprogramming of adult …
Cardiac Tissue Regeneration - The Use Of Stem Cells, Chavy Friedlander
Cardiac Tissue Regeneration - The Use Of Stem Cells, Chavy Friedlander
The Science Journal of the Lander College of Arts and Sciences
The following is the introduction to the article: Cardiovascular disease is the leading cause of illness and fatality. Diseases such as coronary artery disease, myocardial infarction and subsequent congestive heart failure pose a serious problem to much of the population in the Unites States and all over the world. The heart’s compromised function that results from the above conditions is so influential as the heart has little capacity to repair its lost tissue; once the cardiac myocytes are destroyed its effects are amplified by a drastic decrease in cardiac function. Until recently with the advent of stem cell technology, researchers …
