Cells residing in these adjacent yet distinct tissues are regulated by unique mechanisms (<a href="https://pubmed.ncbi.nlm.nih.gov/26657771/">Lim et al. 2016</a>, <a href="https://pubmed.ncbi.nlm.nih.gov/29215029/">Lim et al. 2017</a>). Furthermore, abnormalities in these musculoskeletal resident cell populations can contribute to disease such as osteoarthritis (OA) or temporomandibular joint OA (TMJ-OA) which affects over 15 million individuals in the United States. </p><p>Our overarching goal is (1) to investigate mechanisms of cell differentiation and function that are essential for the development and maintenance of unique cell types that reside in the TMJ, and (2) to determine how alterations in these mechanisms contribute to TMJ-OA and temporomandibular disorders (TMDs). We will address these questions by using multi-disciplinary approaches, including state-of-the-art imaging techniques, single cell and spatial transcriptomics, mouse genetic tools, and 3D in vitro culture models.<br></p> | | | <p></p><p><a href="https://www.ncbi.nlm.nih.gov/myncbi/joohyun.lim.1/bibliography/public/"><strong>Full list of publications</strong></a></p><p><strong>Lim J</strong>, Lietman C, Grol MW, Castellon A, Dawson B, Adeyeye M, Rai J, Weis M, Keene DR, Schweitzer R, Park D, Eyre DR, Krakow D, Lee BH.
