实验数据

Figure 1. Robust Bone Marrow Mesenchymal Stem and Progenitor Cells (BM MSCs) Osteogenic Differentiation is Achieved in 14 days

Human BM MSCs were derived and expanded for 3 passages using the MesenCult™-ACF Culture Kit (Catalog #05449), MesenCult™ Proliferation Kit (Catalog #05411) or in MesenCult™-hPL Medium (05439). Once MSCs reach greater than 95% confluency, MesenCult™ Osteogenic medium was added to each MSC culture. Osteogenic differentiation was observed within 14 days of induction as indicated by strong alkaline phosphatase activity (red stain) and bone mineralization by the von Kossa method (black stain). Negative controls of undifferentiated MSC cultures were kept in each MesenCult™ MSC expansion media for the same time period. Negative Controls show little or no alkaline phosphatase activity and bone mineralization.

Figure 2. MesenCult™ Osteogenic Medium Leads to Faster and Stronger Osteogenic Differentiation When Compared to A Commercial Osteogenic Differentiation Medium

BM MSCs derived and expanded in MesenCult™-ACF or MesenCult™ Proliferation medium were differentiated for 14 days in either MesenCult™ Osteogenic or another Commercial Osteogenic Medium. Differentiation assays using the MesenCult™ Osteogenic medium displayed stronger alkaline phosphatase activity (red stain) and bone mineralization (black stain) when compared to cultures differentiated with a Commercial Osteogenic Medium.

Figure 3. Osteogenic Differentiation of ES-Derived Mesenchymal Progenitor Cells (MPCs)

Mesenchymal progenitor cells (MPCs) were derived from a human iPS or ES cell line using the STEMdiff™ Mesenchymal Progenitor Kit (Catalog #05240) and expanded for 18 or 17 passages, respectively. Cultures of iPS- and ES-derived MPCs were then differentiated for 20 or 27 days in MesenCult™ Osteogenic Differentiation Medium. Strong alkaline phosphatase activity (red stain) and bone mineralization (black stain) were observed at 20 days of osteogenic differentiation, which was further enhanced after 27 days of osteogenic differentiation.

In situ repair abilities of human umbilical cord-derived mesenchymal stem cells and autocrosslinked hyaluronic acid gel complex in rhesus monkeys with intrauterine adhesion. L. Wang et al. Science advances 2020 may

Abstract

Increasing occurrence of moderate to severe intrauterine adhesion (IUA) is seriously affecting the quality of human life. The aim of the study was to establish IUA models in nonhuman primates and to explore the dual repair effects of human umbilical cord-derived mesenchymal stem cells (huMSCs) loaded on autocrosslinked hyaluronic acid gel (HA-GEL) on endometrial damage and adhesion. Here, we recorded the menstrual cycle data in detail with uterine cavities observed and endometrial tissues detected after intervention, and the thicker endometria, decreased amount of fibrotic formation, increased number of endometrium glands, etc., suggested that both HA-GEL and huMSC/HA-GEL complexes could partially repair IUA caused by mechanical injury, but huMSC/HA-GEL complex transplantation had notable dual repair effects: a reliable antiadhesion property and the promotion of endometrial regeneration.
Altered Surface Hydrophilicity on Copolymer Scaffolds Stimulate the Osteogenic Differentiation of Human Mesenchymal Stem Cells. Z. Xing et al. Polymers 2020 jun

Abstract

BACKGROUND Recent studies have suggested that both poly(l-lactide-co-1,5-dioxepan-2-one) (or poly(LLA-co-DXO)) and poly(l-lactide-co-$\epsilon$-caprolactone) (or poly(LLA-co-CL)) porous scaffolds are good candidates for use as biodegradable scaffold materials in the field of tissue engineering; meanwhile, their surface properties, such as hydrophilicity, need to be further improved. METHODS We applied several different concentrations of the surfactant Tween 80 to tune the hydrophilicity of both materials. Moreover, the modification was applied not only in the form of solid scaffold as a film but also a porous scaffold. To investigate the potential application for tissue engineering, human bone marrow mesenchymal stem cells (hMSCs) were chosen to test the effect of hydrophilicity on cell attachment, proliferation, and differentiation. First, the cellular cytotoxicity of the extracted medium from modified scaffolds was investigated on HaCaT cells. Then, hMSCs were seeded on the scaffolds or films to evaluate cell attachment, proliferation, and osteogenic differentiation. The results indicated a significant increasing of wettability with the addition of Tween 80, and the hMSCs showed delayed attachment and spreading. PCR results indicated that the differentiation of hMSCs was stimulated, and several osteogenesis related genes were up-regulated in the 3{\%} Tween 80 group. Poly(LLA-co-CL) with 3{\%} Tween 80 showed an increased messenger Ribonucleic acid (mRNA) level of late-stage markers such as osteocalcin (OC) and key transcription factor as runt related gene 2 (Runx2). CONCLUSION A high hydrophilic scaffold may speed up the osteogenic differentiation for bone tissue engineering.
Human Umbilical Cord Mesenchymal Stem Cells Attenuate Abdominal Aortic Aneurysm Progression in Sprague-Dawley Rats: Implication of Vascular Smooth Muscle Cell Phenotypic Modulation. H. Wen et al. Stem cells and development 2020 jul

Abstract

Abdominal aortic aneurysm (AAA) is life-threatening, for which efficient nonsurgical treatment strategy has not been available so far. Several previous studies investigating the therapeutic effect of mesenchymal stem cells (MSCs) in AAA indicated that MSCs could inhibit aneurysmal inflammatory responses and extracellular matrix destruction, and suppress aneurysm occurrence and expansion. Vascular smooth muscle cell (VSMC) phenotypic plasticity is reported to be predisposed in AAA initiation and progression. However, little is known about the effect of MSCs on VSMC phenotypic modulation in AAA. In this study, we investigate the therapeutic efficacy of umbilical cord mesenchymal stem cells (UC-MSCs) in elastase-induced AAA model and evaluate the effect of UC-MSC on VSMC phenotypic regulation. We demonstrate that the intravenous injection of UC-MSC attenuates elastase-induced aneurysmal expansion, reduces elastin degradation and fragmentation, inhibits MMPs and TNF-$\alpha$ expression, and preserves and/or restores VSMC contractile phenotype in AAA. Taken together, these results highlight the therapeutic and VSMC phenotypic modulation effects of UC-MSC in AAA progression, which further indicates the potential of applying UC-MSC as an alternative treatment candidate for AAA.
