Regenerative medicine is focused on functional restoration of a particular tissue and organs. Stem cell based miniaturized heterogenous cellular clusters named organoids, exhibit features of organ functionality, self-organization, multicellularity, and utility. Induced pluripotent stem cells (iPSCs), have great potential to develop organoids of specific tissues and utilized in regenerative medicine. Organoid technologies have revolutionized the approach to human development and diseases, providing outstanding tools for research and in vitro disease modeling. The goal of this study is to investigate potential metabolites of lacrimal gland organoids from human iPSC-derived multi zonal ocular cells. With the use of metabolomics technologies, we aimed to identify the metabolites present in iPSC derived lacrimal gland (LG) organoids to better understand developmental phases in vitro. Additionally, we investigate the secretion profiles of functional LG organoids upon chemical stimulation. To achieve that we collected cell and supernatant samples of undifferentiated iPSCs, immature and mature LG organoids and analyzed with GC-MS. We identify total 128 and 179 metabolites from cell lysates and from culture supernatant respectively. The data clearly demonstrate the metabolic shifts during the differentiation, maturation and stimulation. Profiling of energy, lipid and amino acid metabolisms of organoids within defined conditions and time course has been successfully elucidated. This work can serve as a model for future organoid research.

Scaffolds produced for tissue engineering applications are promising alternatives to be used in healing and regeneration of injured tissues and organs. In this study, fibrous poly(ε-caprolactone) (PCL) scaffolds were prepared by wet spinning technique and modified by addition of β-tricalcium phosphate (β-TCP) and by immobilizing gelatin onto fibers. Meanwhile, gelatin microspheres carrying Ceftriaxone sodium (CS), a model antibiotic, were added onto the scaffolds and antimicrobial activity of CS was investi...
Integrated biomimetic scaffolds for soft tissue engineering
Güven, Sinan; Hasırcı, Nesrin; Department of Biotechnology (2006)
Tissue engineering has the potential to create new tissue and organs from cultured cells for transplantation. Biodegradable and biocompatible scaffolds play a vital role in the transfer of the cultured cells to a new tissue. Various scaffolds for soft tissue engineering have been developed, however there is not any structure totally mimicking the natural extracellular matrix (ECM), ready to use. In this study biodegradable and biocompatible scaffolds were developed from natural polymers by tissue engineerin...

For materials used in the production of dental and orthopedic implants or scaffolds for bone tissue regeneration, the properties such as capacity to enhance cell attachment and proliferation, and antimicrobial activity to prevent biofilm formation are very important to improve the clinical utility of the material. In this study, poly(epsilon-caprolactone) (PCL) sponges with antimicrobial activity were prepared by incorporating gentamicin loaded beta-tricalcium phosphate (beta-TCP)-Gelatin microspheres, and ...
