Abstract
Introduction: The transportation of tissues from hospitals to clinical laboratories for cell therapy is an essential component of regenerative medicine. Previously, we used laboratory-cultured mucosal cells from buccal epithelium expanded and encapsulated using a scaffold-hybrid approach to the urethral stricture (BEES-HAUS) procedure. In this study, to improve the outcomes, we compared the thermoreversible gelation polymer (TGP) transportation procedure with conventional culture methods, and reported its advantages. Methods: Human buccal mucosal tissues in Phase I of the study were transported in Euro-Collins solution (ECS) and the cells obtained were cultured in two-dimensional (2D) Dulbecco's modified Eagle's medium (DMEM), CnT-Prime epithelial 2D differentiation medium (CnT-PR), and a three-dimensional (3D)-TGP scaffold. In Phase II, tissues were transported in a TGP cocktail and the ECS. The cells were cultured in 2D-DMEM and 3D-TGP, quantified, and characterized by immunohistochemistry. Results: The cells in 3D-TGP culture maintained epithelial morphology in a better manner compared with 2D-DMEM, in which they developed fibroblast-like morphology. The TGP-transported cells grew rapidly. Immunohistochemical analysis results for AE1/AE3, EGFR, integrin-β1, p63, and p75 were intensely positive in 3D-TGP. Conclusion: The TGP-based cocktail used in human buccal tissue transportation yielded cells with better morphology maintenance. The TGP scaffold provides an optimal in vitro environment wherein epithelial cells better maintain their native phenotype compared to those cultured through conventional methods. These results suggest using TGP for the transportation and culture of human buccal tissues for clinical applications. In addition, the use of a TGP-based cocktail for the transport of other tissues for regenerative medicine applications is worth further analysis.

In vitro culture and characterization of enteric neural precursor cells from human gut biopsy specimens using polymer scaffold. Intractable Rare Dis Res 2013; 2:98-102.

Abstract
In vitro expansion and characterization of neural precursor cells from human gut biopsy specimens with or without Hirschsprung's disease using a novel thermoreversible gelation polymer (TGP) is reported aiming at a possible future treatment. Gut biopsy samples were obtained from five patients undergoing gut resection for Hirschsprung's disease (n = 1) or gastrointestinal disorders (n = 4). Cells isolated from the smooth muscle layer and the myenteric plexus were cultured in two groups for 18 to 28 days; Group I: conventional culture as earlier reported and Group II: using TGP scaffold. Neurosphere like bodies (NLBs) were observed in the cultures between 8th to 12th day and H & E staining was positive for neural cells in both groups including aganglionic gut portion from the Hirschsprung's disease patient. Immunohistochemistry using S-100 and neuron specific enolase (NSE) was positive in both groups but the TGP group (Group II) showed more number of cells with intense cytoplasmic granular positivity for both NSE and S-100 compared to Group I. TGP supports the in vitro expansion of human gut derived neuronal cells with seemingly better quality NLBs. Animal Studies can be tried to validate their functional outcome by transplanting the NLBs with TGP scaffolds to see whether this can enhance the outcome of cell based therapies for Hirschsprung's disease.
