Dr. Walid Fakhouri’s research focuses on understanding the genetic and epigenetic regulation of cell fate determination during neural tube and craniofacial development. The Fakhouri Laboratory investigates the function of two developmental genes and their protein activities in regulating cell shape changes and cytoskeletal organization, and how the loss of function can lead to birth defects, including cleft lip and palate, craniosynostosis, and facial dysostosis. His lab uses mouse models, organ cultures, and biochemical assays to delineate further the underlying cellular mechanism and regulatory pathway that drive the proper formation of the neural tube and craniofacial bone development. His research aims to uncover druggable genes and signaling pathways that can be used to prevent and treat congenital birth defects. His lab also investigates the role of the cleft lip and palate gene, IRF6, in salivary gland development and maturation. His research also aims to accelerate the identification of pathological non-coding DNA variations to improve cancer screening and prevention.

Keywords: craniofacial development, cell fate regulation, cleft lip and palate, mandibular disorders, salivary gland development, gene regulation, modeling of pathological non-coding DNA variations.

Dr. Farach-Carson’s research aims to integrate extracellular matrix biology with three fields: a) salivary gland tissue engineering b) cancer biology and metastasis to bone, and (c) bone and cartilage structure-function relations. Three-dimensional engineered microtissue models are used to study the behavior of both normal and aberrant cells and to study their behavior in a physiologically relevant context. Their translational partnerships support the development of new technologies needed to study cell behavior including for regenerative medicine and cancer biology applications.

Keywords: Salivary gland tissue engineering, extracellular matrix, complex 3D systems for culture of both normal and cancerous tissues.

Dr. Daniel Harrington’s research focuses on developing polymeric and supramolecular biomaterials for use in tissue regeneration and in vitro 3D cell culture. Lab members apply functionalized hyaluronan-based hydrogel matrices for salivary cell culture, including multiple biomanufacturing methods such as bioprinting. These same materials also enable our complex in vitro co-cultures of cancer xenografts with associated stromal fibroblasts on a microfluidic platform for drug screening. In his collaborations, the Harrington Laboratory uses self-assembling peptide amphiphile hydrogel platforms for growth factor delivery to promote nerve viability.

Dr. Syed Hashmi’s research focuses on the epidemiological and population-level aspects of birth defects that involve craniofacial structures. He has been involved in various epidemiological and genetic studies on various congenital defects, including research on maternal risk factors during pregnancy (e.g. maternal hyperthermia or folic acid use) that may influence the risk of giving birth to a child with oral clefts. He has expertise working with Big Data and has collaborated with and worked on large datasets from the Texas Birth Defects Epidemiology and Surveillance (BDES) Branch of the Texas Department of State Health Services and the Centers for Disease Control and Prevention (CDC).

Dr. Junichi Iwata’s research is focused on cellular and molecular mechanisms underlying craniofacial birth defects (e.g. cleft lip with/without cleft palate, tooth and musculoskeletal defects) and diseases (e.g. Sjögren’s syndrome). The Iwata Laboratory has been characterizing cellular metabolic processes, membrane trafficking, and non-coding RNAs—which are crucial for craniofacial development and homeostasis—using multidisciplinary approaches including genetics, genomics, proteomics, biochemistry, and molecular biology.

Dr. Yoshihiro Komatsu's research focuses on understanding the molecular mechanisms responsible for human congenital diseases, with an emphasis on craniofacial abnormalities.
