Optimization Of Primary Cilia Detection In Musculoskeletal Tissue, Ragen Engel
Optimization Of Primary Cilia Detection In Musculoskeletal Tissue, Ragen Engel
Williams Honors College, Honors Research Projects
The objective of this research project was to optimize a laboratory technique for visualizing primary cilia in musculoskeletal tissue of young swine, specifically the growth plate of long bones. This was accomplished through varying fixation procedures, antigen retrieval methods, antibody concentrations, and incubation times. By varying these parameters, a reproducible procedure was developed to examine the primary cilia in multiple tissues including ligament, fascia, and growth plate. This experiment introduced variances in fixation methods, with methanol or formalin. Paraffin and frozen embedding techniques were also varied for comparison with regards to cilia visualization. Results from the acetylated alpha tubulin (aTUB) …
Examining The Tissue-Level And Gross Phenotypic Effects Of The Connexin43i130t/+ Mutation On The Developing Mouse Skull, Sommer G.E. Jarvis
Examining The Tissue-Level And Gross Phenotypic Effects Of The Connexin43i130t/+ Mutation On The Developing Mouse Skull, Sommer G.E. Jarvis
Electronic Thesis and Dissertation Repository
The purpose of this study was to investigate the effects of reduced Connexin43 function on the developing skull phenotype, osteoblast and chondrocyte proliferation and differentiation, and to determine if a correlation exists between cell processes and gross morphology. Using the Cx43I130T/+mouse model, skull shape was analyzed using geometric morphometrics and cell proliferation and differentiation were assessed using immunohistochemistry at late embryonic and early post-natal stages. The largest shape changes between Cx43I130T/+ and wildtype mice were observed in the cranial base and facial skeleton. Changes infacial morphology correspond to reduced osteoblast differentiation. However, no changes in chondrocyte proliferation …

Macrophages have well-characterized roles in skeletal muscle repair and regeneration. Relatively little is known regarding the role of resident macrophages in skeletal muscle homeostasis, extracellular matrix remodeling, growth, metabolism and adaptation to various stimuli including exercise and training. Despite speculation into macrophage contributions during these processes, studies characterizing macrophages in non-injured muscle are limited and methods used to identify macrophages vary. A standardized method for the identification of human resident skeletal muscle macrophages will aide in the characterization of these immune cells and allow for the comparison of results across studies. Here, we present an immunohistochemistry (IHC) protocol, validated by …
