Myogenesis involves skeletal muscle stem cells (MuSCs) that produce and regenerate skeletal muscle during regular growth and repair. However, when this system fails to function normally, it can lead to musculoskeletal diseases like Duchenne Muscular Dystrophy (DMD). Therefore, it is important to study the molecular mechanisms behind this developmental process in order to seek therapies and solutions for these types of diseases. Our interest lies in the field of epitranscriptomics, which focuses on post-transcriptional ribonucleic acid (RNA) modifications, particularly N6-methyladenosine (m6A), which involves the addition of a methyl group to the adenosine nucleotide, a process that is mediated by the …

Organogenesis is the process organs go through where cellular communications coordinate all a developing organ needs. What organs need are more cells, in the right place, doing the right job. In the salivary gland, we know that stromal cells are important for organogenesis and that they coordinate the epithelium’s form and functions. However, specific stromal contributions have focused on epithelial quantity and placement. There is less information about how the stroma directs the epithelium towards certain functions. Here we used organoids as a model for understanding what stromal signaling directs epithelial cell fate. We found that stromal cell state is …

Germ cells give rise to gametes and link generations by passing genetic information from parent to offspring. Gametes arise from, in many sexually reproducing organisms, germline stem cells (GSCs) which are set aside early during development. GSCs have an amazing capacity to undergo self-renewal to give rise to a pool of undifferentiated cells, while also differentiating to generate specialized germ cells such as haploid gametes. Upon female GSC differentiation, mitotically dividing germ cells can initiate meiosis, and mature within a follicle. During maturation, the specified oocyte is provided with a trust fund of RNAs and proteins for the next generation …

The Influence Of Mir-322 On Skeletal Muscle Differentiation, Miles Alexander Soyer
Legacy Theses & Dissertations (2009 - 2024)
Skeletal muscle plays a crucial role in coordinating voluntary movement and accounts for nearly 50% of total body mass. Dysregulation in skeletal muscle development is known to cause muscle degenerative diseases including the devastating Duchenne Muscular Dystrophy (DMD). The majority of the biological studies investigating muscle development were based on myogenic transcription factors and signaling molecules including: Pax7, Myf5, MyoD, WNT, TGF-β and BMP. After the discovery of non-coding RNAs including microRNAs, it was postulated that these molecules could regulate gene expression and thus affect differentiation and development. MicroRNAs are small non-coding RNAs (~17-25 nucleotides) that regulate gene expression negatively …

The salivary gland is an organ often taken for granted by most people. However, its proper function is essential for several everyday activities, such as speaking, swallowing, and tasting. As such, impaired salivary gland function, such as that caused by Sjögren’s Syndrome or radiotherapy for head and neck cancers, can lead to a significantly reduced quality of life. The cells that produce saliva in salivary glands are known as acinar cells, which arise from proacinar cells generated during embryonic development. As such, in studying the promoter regions of proacinar and acinar genes, it may be possible to identify common transcription …

Controlled expansion and differentiation of progenitor cell populations is essential for organogenesis followed by continued maintenance of the population into and through adulthood. As the K5+ basal cell population is regulated by retinoic acid signaling, we interrogated the contribution of specific RAR isoforms to the regulation of these cells during submandibular salivary gland (SMG) organogenesis and regeneration. Retinoic acid has previously been shown to be involved in the development of the salivary gland, and recently, lack of retinoid signaling has been shown to impact the K5+ population of basal progenitor cells. Since retinoic acid is known to exert stimulatory effects …

Germ cells are the only cell in an organism that have the capacity to give rise to a new organism and are passed from one generation to the next. Therefore, to maintain this unique ability of totipotency and immortality, germ cells execute specific functions, such as, repression of a somatic program and contour a germ line-specific pre- and post-transcriptional gene regulatory landscape. In many sexually reproducing organisms, germ cells are formed during the earliest stages of embryogenesis and undergoes several stages of development to eventually get encapsulated by the somatic cells of the gonad. Once, in the gonad, the germ …

Stem cells have the unique capability of self-renewing into stem cells and differentiating into several terminal cell types. Loss of either of these processes can lead to aging, progression towards degenerative diseases and cancers. Insight into how self-renewal and differentiation are regulated will have tremendous therapeutic impact. Drosophila is an excellent model system for stem cell study due to the availability of various mutants, markers and RNAi technology. In order to study stem cell biology, we use female Drosophila gonads, whose stem cell population – the germline stem cells (GSCs) gives rise to gametes.

Organogenesis is the process by which tissues organize, gain considerable size, and undergo cellular differentiation or specialization to form fully functional organs. To study the processes involved in organogenesis of branched organs, the mouse submandibular salivary gland is frequently used as a model system, as it can undergo morphogenesis and differentiation and be genetically manipulated ex vivo. The mouse submandibular salivary gland undergoes a specific process of outgrowth and invagination known as branching morphogenesis which allows for the significant increase in gland size and complexity, as well as maximization of surface area for secretion of saliva. Surrounding the mouse submandibular …

The development of submandibular salivary glands is complex and requires coordination of specific signaling events. Submandibular salivary glands originate as an epithelial invagination into the adjacent mesenchyme that leads to a single stalk and end bud; this end bud will go through a clefting process. Numerous rounds of clefting will lead to a fully developed salivary gland by this process, which is known as branching morphogenesis. As the gland undergoes morphogenesis, specific cues leading to differentiation of multiple cell types and even epithelial sub classes are required. By the later stages of development the glands are fully innervated, have an …
