Nanotopography reveals metabolites that maintain the immunomodulatory phenotype of mesenchymal stromal cells. Nat Commun 2023; 14:753. [PMID: 36765065 PMCID: PMC9918539 DOI: 10.1038/s41467-023-36293-7] [Citation(s) in RCA: 8] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/09/2021] [Accepted: 01/25/2023] [Indexed: 02/12/2023] Open
Abstract
Mesenchymal stromal cells (MSCs) are multipotent progenitor cells that are of considerable clinical potential in transplantation and anti-inflammatory therapies due to their capacity for tissue repair and immunomodulation. However, MSCs rapidly differentiate once in culture, making their large-scale expansion for use in immunomodulatory therapies challenging. Although the differentiation mechanisms of MSCs have been extensively investigated using materials, little is known about how materials can influence paracrine activities of MSCs. Here, we show that nanotopography can control the immunomodulatory capacity of MSCs through decreased intracellular tension and increasing oxidative glycolysis. We use nanotopography to identify bioactive metabolites that modulate intracellular tension, growth and immunomodulatory phenotype of MSCs in standard culture and during larger scale cell manufacture. Our findings demonstrate an effective route to support large-scale expansion of functional MSCs for therapeutic purposes.

Impact of Microenvironmental Changes during Degeneration on Intervertebral Disc Progenitor Cells: A Comparison with Mesenchymal Stem Cells. Bioengineering (Basel) 2022; 9:bioengineering9040148. [PMID: 35447707 PMCID: PMC9025850 DOI: 10.3390/bioengineering9040148] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2022] [Revised: 03/16/2022] [Accepted: 03/17/2022] [Indexed: 12/22/2022] Open
Abstract
Intervertebral disc (IVD) degeneration occurs with natural ageing and is linked to low back pain, a common disease. As an avascular tissue, the microenvironment inside the IVD is harsh. During degeneration, the condition becomes even more compromised, presenting a significant challenge to the survival and function of the resident cells, as well as to any regeneration attempts using cell implantation. Mesenchymal stem cells (MSCs) have been proposed as a candidate stem cell tool for IVD regeneration. Recently, endogenous IVD progenitor cells have been identified inside the IVD, highlighting their potential for self-repair. IVD progenitor cells have properties similar to MSCs, with minor differences in potency and surface marker expression. Currently, it is unclear how IVD progenitor cells react to microenvironmental factors and in what ways they possibly behave differently to MSCs. Here, we first summarized the microenvironmental factors presented in the IVD and their changes during degeneration. Then, we analyzed the available studies on the responses of IVD progenitor cells and MSCs to these factors, and made comparisons between these two types of cells, when possible, in an attempt to achieve a clear understanding of the characteristics of IVD progenitor cells when compared to MSCs; as well as, to provide possible clues to cell fate after implantation, which may facilitate future manipulation and design of IVD regeneration studies.

Hypoxia-Preconditioned Human Umbilical Cord Blood-Derived Mesenchymal Stem Cells Mitigate Hypoglycemic Testicular Injury Induced by Insulin in Rats. Cells Tissues Organs 2020; 209:83-100. [PMID: 33113534 DOI: 10.1159/000510363] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2020] [Accepted: 07/22/2020] [Indexed: 11/19/2022] Open
Abstract
Hypoglycemia is a neglected metabolic disorder. Thus, we evaluated the protective effect of hypoxia-preconditioned human umbilical cord blood-derived mesenchymal stem cells (hUCB-MSCs) on hypoglycemic testicular injury. We examined 56 testes from 28 animals: 7 rats with insulin-induced hypoglycemia (HG group), 7 hypoglycemic rats which received an intratesticular injection of hUCB-MSCs (HG-MSC group), and 14 untreated control rats. Testosterone level, testicular catalase (CAT) activity, and malondialdehyde (MDA) level were analyzed. Immunostaining for specific testicular germ and somatic cell markers was performed. Proliferating and apoptotic cells were detected by anti-PCNA and anti-caspase-3, respectively. Morphometrical data were statistically analyzed. The hypoglycemic rats showed a significant decrease in testosterone level and CAT activity and a significant increase in MDA production. Examination of histological structure and protein expression of diverse germ cell markers revealed collapsed tubules that were lined by degenerated germ cells, decreased lactate dehydrogenase type C immune expression, as well as decreased proliferating and increased apoptotic cells number in hypoglycemic testes. Injection of MSCs improved testicular biochemical parameters, preserved germ cells and somatic cells, and decreased apoptosis. In conclusion, hypoxia-preconditioned hUCB-MSCs attenuate rat testicular injury caused by insulin-induced hypoglycemia. Avoidance and rapid management of hypoglycemia are necessary to avoid significant testicular injury.
