In Vitro Gametogenesis: A Research Timeline And Implications For The Future Of Assisted Reproductive Technology, Nicole Buckley
In Vitro Gametogenesis: A Research Timeline And Implications For The Future Of Assisted Reproductive Technology, Nicole Buckley
Senior Honors Theses
The novel reproductive technology, In Vitro Gametogenesis (IVG), includes the process of obtaining mature viable germ cells from pluripotent stem cells. To do so, embryonic stem cells and induced pluripotent stem cells are specified to primordial germ cells and differentiated to form gametes that undergo further maturation, which subsequently may undergo in vitro fertilization to form an embryo. With this capability, IVG holds the power to provide a novel treatment option for human infertility. As of now, research has been conducted on mice successfully, and with limited success in humans. Future research will likely focus on discovering the species-specific differences …

Cholesterol is a key component of all mammalian cell membranes. Disruptions in cholesterol metabolism have been observed in the context of various diseases, including neurodegenerative disorders such as Alzheimer's disease (AD). The genetic and pharmacological blockade of acyl-CoA:cholesterol acyltransferase 1/sterol O-acyltransferase 1 (ACAT1/SOAT1), a cholesterol storage enzyme found on the endoplasmic reticulum (ER) and enriched at the mitochondria-associated ER membrane (MAM), has been shown to reduce amyloid pathology and rescue cognitive deficits in mouse models of AD. Additionally, blocking ACAT1/SOAT1 activity stimulates autophagy and lysosomal biogenesis; however, the exact molecular connection between the ACAT1/SOAT1 blockade and these observed benefits remain …

The role of ribosome recycling factor (RRF) of E. coli was studied in vivo and in vitro. We used the translational coupling without the Shine-Dalgarno sequence of downstream ORF (d-ORF) as a model system of the RRF action in natural termination of protein synthesis. For the in vivo studies we used the translational coupling by the adjacent coat and lysis genes of RNA phage GA sharing the termination and initiation (UAAUG) and temperature sensitive RRF. The d-ORF translation was measured by the expression of the reporter lacZ gene connected to the 5'-terminal part of the lysis gene. The results showed …

Effect Of Stretch And Release On Myofascial Stem Cell Function In Vitro: A Putative Model To Understand The Molecular Benefits Of The Myofascial Release (Mfr) Technique, Ben Smith, Shahn Notta, Debasis Mondal
Research Day
Despite the beneficial effects of osteopathic manipulative techniques (OMT), there is a lack of in vitro models to understand the molecular mechanisms associated with these time-tested therapies. The Myofascial Release (MFR) technique is a non-invasive approach that involves passive stretching, hold and release, of the soft tissue to achieve myofascial homeostasis. Tissue-resident mesenchymal stem cells (MSC) can regulate the myofascial microenvironment by altering their secreted factors following stretch and release. Therefore, we initiated studies to develop an in vitro model to investigate the possible effects of stretch and release on MSC function, i.e. proliferation and differentiation capabilities, and changes in …
