Abstract
Oral mucosa and salivary gland are composed of complex and dynamic networks of extracellular matrix, multiple cell types, vasculature, and various biochemical agents. Two-dimensional (2D) cell culture is commonly used in testing new drugs and experimental therapies. However, 2D cell culture cannot fully replicate the architecture, physiological, and pathological microenvironment of living human oral mucosa and salivary glands. Recent microengineering techniques offer state of the science cell culture models that can recapitulate human organ structures and functions. This narrative review describes emerging in vitro models of oral and salivary gland tissue such as 3D cell culture models, spheroid and organoid models, tissue-on-a-chip, and functional decellularized scaffolds. Clinical applications of these models are also discussed in this review.

[PMID: 32606281 PMCID: PMC7338634 DOI: 10.5125/jkaoms.2020.46.3.197] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2019] [Revised: 12/12/2019] [Accepted: 12/17/2019] [Indexed: 11/07/2022] Open
Abstract
Objectives We compared the outcomes of two different doses of FK506 (tacrolimus) for immunosuppression in submandibular salivary gland (SMG) allotransplantation. Materials and Methods Three SMG allotransplantation groups were established (n=6 per group) as follows: allograft rejection control (Allo-Ctrl), low dose (0.08 mg/kg) of FK506 (FK506-L), and high dose (0.16 mg/kg) of FK506 (FK506-H). Allograft survival and rejection were assessed by clinical observation, interleukin-2 levels as determined by enzyme-linked immunosorbent assay, blood sampling for complete blood count (CBC), and histological evaluation. Results Body weight and anorexia were higher in the FK506-H group but without a significant difference compared with the FK506-L population. CBC revealed a non-significantly reduced number of changes in the FK506-L group. Four glands in the FK506-H group and two glands in the FK506-L group were viable and functioning post-transplantation. Conclusion The survival rate of allotransplanted glands was higher in conjunction with the high dose of 0.16 mg/kg of FK506, with no major difference in the side-effect profile when compared with the low dose of 0.08 mg/kg short-term outcomes.
