Analysis of cognitive framework and biomedical translation of tissue engineering in otolaryngology. Sci Rep 2023; 13:13492.

Abstract
Tissue engineering is a relatively recent research area aimed at developing artificial tissues that can restore, maintain, or even improve the anatomical and/or functional integrity of injured tissues. Otolaryngology, as a leading surgical specialty in head and neck surgery, is a candidate for the use of these advanced therapies and medicinal products developed. Nevertheless, a knowledge-based analysis of both areas together is still needed. The dataset was retrieved from the Web of Science database from 1900 to 2020. SciMAT software was used to perform the science mapping analysis and the data for the biomedical translation identification was obtained from the iCite platform. Regarding the analysis of the cognitive structure, we find consolidated research lines, such as the generation of cartilage for use as a graft in reconstructive surgery, reconstruction of microtia, or the closure of perforations of the tympanic membrane. This last research area occupies the most relevant clinical translation with the rest of the areas presenting a lower translational level. In conclusion, Tissue engineering is still in an early translational stage in otolaryngology, otology being the field where most advances have been achieved. Therefore, although otolaryngologists should play an active role in translational research in tissue engineering, greater multidisciplinary efforts are required to promote and encourage the translation of potential clinical applications of tissue engineering for routine clinical use.

Minor salivary gland stem cells: a comparative study of the biological properties under clinical-grade culture conditions. Cell Tissue Res 2023; 393:321-342. [PMID: 37249709 PMCID: PMC10406694 DOI: 10.1007/s00441-023-03789-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2022] [Accepted: 05/12/2023] [Indexed: 05/31/2023]
Abstract
Development of clinical-grade, cell preparations is central to cGMP (good manufacturing practice compliant) conditions. This study aimed to investigate the potential of two serum/xeno-free, cGMP (StemPro, StemMacs) culture media to maintain "stemness" of human minor salivary gland stem cell (mSG-SC) cultures compared to a complete culture medium (CCM). Overall, StemMacs resulted in higher proliferation rates after p.6 compared to the conventional serum-based medium, while StemPro showed substantial delays in cell proliferation after p.9. The mSG-SCs cultures exhibited two distinct cell populations at early passages a mesenchymal subpopulation and an epithelial-like subpopulation. Expression of several markers (CD146, STRO-1, SSEA-4, CD105, CD106, CD34, K 7/8, K14, K18) variably decreased with prolonged passaging (all three media). The percentage of SA-β-gal positive cells was initially higher for StemMacs compared to StemPro/CCM and increased with prolonged passaging in all cases. The telomere fragment length decreased with prolonged passaging in all three media but more pronouncedly for the CCM. Expansion under serum-free conditions caused pronounced upregulation of ALP and BMP-2, with parallel complete elimination of the baseline expressions of LPL (all three media) and ACAN (serum-free media), therefore, showing a preferential shift of the mSG-SCs towards osteogenic phenotypes. Finally, several markers (Nanog, SOX-2, PDX-1, OTX2, GSC, HCG) decreased with prolonged culture, indicating successive loss of "stemness". Based on the findings, it seems that StemPro preserve stemness of the mSG-SCs after prolonged culture. Nevertheless, there is still a vacant role for the ideal development of clinical-grade culture conditions.

Abstract
Stem cell research is one of the most rapidly expanding field of medicine which provides significant opportunities for therapeutic and regenerative applications. Different types of stem cells have been isolated investigating their accessibility, control of the differentiation pathway and additional immunomodulatory properties. Bulk of the literature focus has been on the study and potential applications of adult stem cells (ASC) because of their low immunogenicity and reduced ethical considerations. This review paper summarizes the basic available literature on different types of ASC with special focus on stem cells from dental and orofacial origin. ASC have been isolated from different sources, however, isolation of ASC from orofacial tissues has provided a novel promising alternative. These cells offer a great potential in the future of therapeutic and regenerative medicine because of their remarkable availability at low cost while allowing minimally invasive isolation procedures. Furthermore, their immunomodulatory and anti-inflammatory potential is of particular interest. However, there are conflicting reports in the literature regarding their particular biology and full clinical potentials. Sound knowledge and higher control over proliferation and differentiation mechanisms are prerequisites for clinical applications of these cells. Therefore, further standardized basic and translational studies are required to increase the reproducibility and reduce the controversies of studies, which in turn facilitate comparison of related literature and enhance further development in the field.

Abstract
Numerous studies' attempts to improve radiation-induced oral mucositis have not produced a qualified treatment yet. Our aim was to investigate the effectiveness of Korean red ginseng (KRG) on radiation-induced damage in an in vivo rat model. After 20 Gy of irradiation, rats were divided randomly into the following 4 groups: control, KRG only, radiotherapy (RT) only, and RT + KRG group. The rats were monitored in terms of survival rate, activity, mucositis grade, oral intake, and body weight. The tongue, buccal mucosa, and submandibular gland (SMG) were harvested, and the weight of the SMG was analyzed. The samples then underwent hematoxylin and eosin, TUNEL, and immunohistochemical staining. Radiation-induced severe oral mucositis and SMG injury led to poor oral intake and delayed healing, resulting in the death of some rats. We found that survival rate, oral intake, and body weight increased. Moreover, rats treated with KRG showed less severe mucositis and decreased histologic changes of the oral mucosa and SMG. Furthermore, we showed that the protective effects of KRG were caused by inhibition of the apoptotic signal transduction pathway linked to caspase-3. In conclusion, KRG protects the oral mucosa and SMG from radiation-induced damage by inhibiting caspase-mediated apoptosis in rats.

Abstract
Stem cells are of outstanding interest for a variety of applications in regenerative medicine. The identification and characterization of novel tissue sources in order to reduce donor site morbidity and to provide specific cells in clinically applicable numbers have led to the detection of stem cells in almost all adult tissues. Salivary glands are of specific interest to our lab, as these tissues are easily accessible for the head and neck surgeon with low donor site morbidity. On the other hand, they possess an endocrine and exocrine function and thus play a very specific role in the human body. Stem cell identity however can only be demonstrated using a combination of different methods in vitro, as there is not a single marker or feature allowing for definite identification of such cells. In this chapter, we provide a comprehensive summary of our experimental methods for the isolation and characterization of human salivary gland stem cells in vitro.
