Neonatal Islet-1+ Cardiovascular Progenitor Cell-Derived Exosomes And Their Functional Ability To Regulate Proliferation, Lourdes Ceja Aug 2022

Neonatal Islet-1+ Cardiovascular Progenitor Cell-Derived Exosomes And Their Functional Ability To Regulate Proliferation, Lourdes Ceja

Electronic Theses, Projects, and Dissertations

Heart failure affects many people around the world and can lead to disease progression and death. Consequently, new stem and exosome-based therapies are needed to address this major health issue and to provide therapeutic options that will improve outcomes for the increasing number of patients with heart disease. Stem cell-derived exosomes have captivated researchers’ attention over the past couple of years based on their functional role in cellular signaling which highlights the vital component of the secretome of stem and progenitor cells. Since neonates have significantly enhanced regenerative ability, we hypothesized that exosomes isolated from Islet-1+ expressing neonatal human cardiovascular …


When Problems Become Solutions: Harnessing The Osteogenic Capacity Of Disease-Causing Stem Cells To Repair Bone Fractures, Mehreen Pasha May 2022

When Problems Become Solutions: Harnessing The Osteogenic Capacity Of Disease-Causing Stem Cells To Repair Bone Fractures, Mehreen Pasha

University Scholar Projects

While we often perceive disease as negative, there is potential to engineer seemingly negative biological phenomena into therapeutics to treat a variety of human illnesses. Fibrodysplasia ossificans progressiva (FOP) is a genetic disorder involving uncontrolled, widespread, extraskeletal bone growth, or heterotopic ossification (HO). In FOP patients, stem cells called fibro/adipogenic progenitors (FAPs) follow an abnormal, osteogenic pathway. In the present study, we investigate whether we can adapt these Acvr1 mutant FAPs, which are exceptional at producing bone, to repair bone fractures in otherwise normal patients. The primary aims of this study are (1) to devise and optimize a novel method …

Determining Haplotype Specific X Chromosome Inactivation State And Related Epigenetic Features In Female X-Linked Genes, Ariah Dawn Mackie Jan 2022

Determining Haplotype Specific X Chromosome Inactivation State And Related Epigenetic Features In Female X-Linked Genes, Ariah Dawn Mackie

Cal Poly Humboldt theses and projects

Females with heterozygous X-linked mutations are prone to pseudo-haploinsufficiency because random X chromosome inactivation (XCI) silences one of their two X chromosomes. A prior study explored the theory that reactivating the silenced healthy allele could be a treatment for pseudo-haploinsufficient females. The next step was to evaluate this approach in a clinically relevant stem cell model of the rare neurological disease CDKL5 Deficiency Disorder (CDD). It was necessary to validate X-inactivation state with respect to CDKL5 allele expression in one of these models. We explored CDKL5 allele expression in two populations of CDD female patient-derived induced pluripotent stem cells (iPSCs) …
