Abstract
Angiogenesis is considered a hallmark pathophysiological process in tumor development. Aberrant vasculature resulting from tumor angiogenesis plays a critical role in the development of resistance to breast cancer treatments, via exacerbation of tumor hypoxia, decreased effective drug concentrations within tumors, and immune-related mechanisms. Antiangiogenic therapy can counteract these breast cancer resistance factors by promoting tumor vascular normalization. The combination of antiangiogenic therapy with chemotherapy, targeted therapy, or immunotherapy has emerged as a promising approach for overcoming drug resistance in breast cancer. This review examines the mechanisms associated with angiogenesis and the interactions among tumor angiogenesis, the hypoxic tumor microenvironment, drug distribution, and immune mechanisms in breast cancer. Furthermore, this review provides a comprehensive summary of specific antiangiogenic drugs, and relevant studies assessing the reversal of drug resistance in breast cancer. The potential mechanisms underlying these interventions are discussed, and prospects for the clinical application of antiangiogenic therapy to overcome breast cancer treatment resistance are highlighted.

Designer umbilical cord-stem cells induce alveolar wall regeneration in pulmonary disease models. Front Immunol 2024; 15:1384718. [PMID: 38745668 PMCID: PMC11091323 DOI: 10.3389/fimmu.2024.1384718] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2024] [Accepted: 04/02/2024] [Indexed: 05/16/2024] Open
Abstract
Background Researchers are focusing on cellular therapy for chronic obstructive pulmonary disease (COPD) using mesenchymal stem cells (MSCs), with human bone marrow-derived MSCs (hBM-MSCs) leading the way. However, BM-MSCs may not be as optimal as therapeutic cells owing to their low growth potential, invasive harvesting, and high expression of aging-related genes with poor differentiation potential. Consequently, umbilical cord-derived MSCs (hUC-MSCs), which have many excellent features as allogeneic heterologous stem cells, have received considerable attention. Allogeneic and heterologous hUC-MSCs appear to be promising owing to their excellent therapeutic properties. However, MSCs cannot remain in the lungs for long periods after intravenous infusion. Objective To develop designer hUC-MSCs (dUC-MSCs), which are novel therapeutic cells with modified cell-adhesion properties, to aid COPD treatment. Methods dUC-MSCs were cultured on type-I collagen gels and laminin 411, which are extracellular matrices. Mouse models of elastase-induced COPD were treated with hUC-MSCs. Biochemical analysis of the lungs of treated and control animals was performed. Results Increased efficiency of vascular induction was found with dUC-MSCs transplanted into COPD mouse models compared with that observed with transplanted hUC-MSCs cultured on plates. The transplanted dUC-MSCs inhibited apoptosis by downregulating pro-inflammatory cytokine production, enhancing adhesion of the extracellular matrix to alveolar tissue via integrin β1, promoting the polarity of M2 macrophages, and contributing to the repair of collapsed alveolar walls by forming smooth muscle fibers. dUC-MSCs inhibited osteoclastogenesis in COPD-induced osteoporosis. hUC-MSCs are a promising cell source and have many advantages over BM-MSCs and adipose tissue-derived MSCs. Conclusion We developed novel designer cells that may be involved in anti-inflammatory, homeostatic, injury repair, and disease resistance processes. dUC-MSCs repair and regenerate the alveolar wall by enhancing adhesion to the damaged site. Therefore, they can contribute to the treatment of COPD and systemic diseases such as osteoporosis.

Abstract
Breast cancer has become the most diagnosed cancer type, endangering the health of women. Patients with breast resection are likely to suffer serious physical and mental trauma. Therefore, breast reconstruction becomes an important means of postoperative patient rehabilitation. Polyvinyl alcohol hydrogel has great potential in adipose tissue engineering for breast reconstruction. However, its application is limited because of the lack of bioactive factors and poor structural stability. In this study, we prepared biodegradable polylactic acid-glycolic acid copolymer/polycaprolactone/gelatin (PPG) nanofibers. We then combined them with polyvinyl alcohol/collagen to create tissue engineering scaffolds to overcome limitations. We found that PPG fibers formed amide bonds with polyvinyl alcohol/collagen scaffolds. After chemical crosslinking, the number of amide bonds increased, leading to a significant improvement in their mechanical properties and thermal stability. The results showed that compared with pure PVA scaffolds, the maximum compressive stress of the scaffold doped with 0.9 g nanofibers increased by 500 %, and the stress loss rate decreased by 40.6 % after 10 cycles of compression. The presence of natural macromolecular gelatin and the changes in the pore structure caused by nanofibers provide cells with richer and more three-dimensional adsorption sites, allowing them to grow in three dimensions on the scaffold. So, the hydrogel scaffold by reinforcing polyvinyl alcohol hydrogel with PPG fibers is a promising breast reconstruction method.

Abstract
Inadequate vascularization is a significant barrier to clinical application of large-volume tissue engineered grafts. In contrast to in vivo vascularization, in vitro prevascularization shortens the time required for host vessels to grow into the graft core and minimizes necrosis in the core region of the graft. However, the challenge of prevascularization is to construct hierarchical perfusable vascular networks, increase graft volume, and form a vascular tip that can anastomose with host vessels. Understanding advances in in vitro prevascularization techniques and new insights into angiogenesis could overcome these obstacles. In the present review, we discuss new perspectives on angiogenesis, the differences between in vivo and in vitro tissue vascularization, the four elements of prevascularized constructs, recent advances in perfusion-based in vitro prevascularized tissue fabrication, and prospects for large-volume prevascularized tissue engineering.

Abstract
There are many gynecological diseases, among which breast cancer (BC), cervical cancer (CC), endometriosis (EMs), and polycystic ovary syndrome (PCOS) are common and difficult to cure. Stem cells (SCs) are a focus of regenerative medicine. They are commonly used to treat organ damage and difficult diseases because of their potential for self-renewal and multidirectional differentiation. SCs are also commonly used for difficult-to-treat gynecological diseases because of their strong directional differentiation ability with unlimited possibilities, their tendency to adhere to the diseased tissue site, and their use as carriers for drug delivery. SCs can produce exosomes in a paracrine manner. Exosomes can be produced in large quantities and have the advantage of easy storage. Their safety and efficacy are superior to those of SCs, which have considerable potential in gynecological treatment, such as inhibiting endometrial senescence, promoting vascular reconstruction, and improving anti-inflammatory and immune functions. In this paper, we review the mechanisms of the regenerative and anti-inflammatory capacity of SCs and exosomes in incurable gynecological diseases and the current progress in their application in genetic engineering to provide a foundation for further research.

Skin precursor‐derived Schwann cells accelerate in vivo prevascularization of tissue‐engineered nerves to promote peripheral nerve regeneration. Glia 2023; 71:1755-1769.

Abstract
Prevascularization strategies have become a hot spot in tissue engineering. As one of the potential candidates for seed cells, skin precursor-derived Schwann cells (SKP-SCs) were endowed with a new role to more efficiently construct prevascularized tissue-engineered peripheral nerves. The silk fibroin scaffolds seeded with SKP-SCs were prevascularized through subcutaneously implantation, which was further assembled with the SKP-SC-containing chitosan conduit. SKP-SCs expressed pro-angiogenic factors in vitro and in vivo. SKP-SCs significantly accelerated the satisfied prevascularization in vivo of silk fibroin scaffolds compared with VEGF. Moreover, the NGF expression revealed that pregenerated blood vessels adapted to the nerve regeneration microenvironment through reeducation. The short-term nerve regeneration of SKP-SCs-prevascularization was obviously superior to that of non-prevascularization. At 12 weeks postinjury, both SKP-SCs-prevascularization and VEGF-prevascularization significantly improved nerve regeneration with a comparable degree. Our figures provide a new enlightenment for the optimization of prevascularization strategies and how to further utilize tissue engineering for better repair.

Abstract
Mesenchymal stem cells (MSCs) are adult stem cells that reside in almost all postnatal tissues where, due to the potent regenerative, pro-angiogenic and immunomodulatory properties, regulate tissue homeostasis. Obstructive sleep apnea (OSA) induces oxidative stress, inflammation and ischemia which recruit MSCs from their niches in inflamed and injured tissues. Through the activity of MSC-sourced anti-inflammatory and pro-angiogenic factors, MSCs reduce hypoxia, suppress inflammation, prevent fibrosis and enhance regeneration of damaged cells in OSA-injured tissues. The results obtained in large number of animal studies demonstrated therapeutic efficacy of MSCs in the attenuation of OSA-induced tissue injury and inflammation. Herewith, in this review article, we emphasized molecular mechanisms which are involved in MSC-based neo-vascularization and immunoregulation and we summarized current knowledge about MSC-dependent modulation of OSA-related pathologies.

Abstract
The role of mesenchymal stem cells (MSCs) in the breast tumor microenvironment (TME) is significant and multifaceted. MSCs are recruited to breast tumor sites through molecular signals released by tumor sites. Once in the TME, MSCs undergo polarization and interact with various cell populations, including immune cells, cancer-associated fibroblasts (CAFs), cancer stem cells (CSCs), and breast cancer cells. In most cases, MSCs play roles in breast cancer therapeutic resistance, but there is also evidence that indicates their abilities to sensitize cancer cells to chemotherapy and radiotherapy. MSCs possess inherent regenerative and homing properties, making them attractive candidates for cell-based therapies. Therefore, MSCs can be engineered to express therapeutic molecules or deliver anti-cancer agents directly to tumor sites. Unraveling the intricate relationship between MSCs and the breast TME has the potential to uncover novel therapeutic targets and advance our understanding of breast cancer biology.

Abstract
BACKGROUND Angiogenesis is a pathological phenomenon contribute to the development of chronic liver diseases, and anti-angiogenic therapy is an effective strategy to alleviate liver fibrosis. Carthami flos, a medicinal and edible herb, has the effects of improving blood circulation and regulating angiogenesis. However, the anti-angiogenic effect of Carthami flos in liver fibrosis remains unknown. METHODS We investigated the protective effect and therapeutic mechanism of Carthami flos extract (CFE) on carbon tetrachloride (CCl4)-induced liver fibrosis in mice. The liver injury and collagen deposition were observed and evaluated by conducting HE, Masson, and Sirius red staining, testing the serum biochemical indexes (ALT, AST, ALP, γ-GT), and measuring the contents of HYP and four indexes of liver fiber (Col-IV, LN, HA, PC-III). Simultaneously, the expressions of α-SMA and Collagen-I were detected to determine the activation of hepatic stellate cells (HSCs). Subsequently, we measured the expressions of angiogenesis-related proteins such as PDGFRB, ERK1/2, p-ERK1/2, MEK, p-MEK, HIF-1α, VEGFA, VEGFR2, AKT and eNOS, and the mRNA levels of PDGFRB and VEGFA. Additionally, immunofluorescence staining and RT-qPCR assays were carried out to ascertain the expressions of continuous endothelial markers CD31, CD34 and vWF, and scanning electron microscope analysis was performed to observe the number of sinusoidal endothelial fenestrations. RESULTS Herein, we found that CFE could significantly reduce liver injury and collagen deposition, like the same effect of colchicine. CFE significantly alleviated CCl4-induced liver injury and fibrosis, mainly manifested by reducing the levels of ALT, AST, ALP and γ-GT and decreasing the contents of HYP, Col-IV, LN, HA and PC-III. Additionally, CCl4 promoted the activation of HSCs by increasing the expressions of α-SMA and Collagen-I, while CFE could rectify the condition. Moreover, CFE treatment prevented the CCl4-induced the up-regulation of PDGFRB, p-MEK, p-ERK1/2, HIF-1α, VEGFA, VEGFR2, AKT and eNOS, suggesting that CFE might provide the protection against abnormal angiogenesis. In the meantime, the gradual disappearance of sinusoidal capillarization after CFE treatment was supported by the decreased the contents of CD31, CD34 and vWF, as well as the increased number of sinusoidal endothelial fenestrae. CONCLUSION In this study, the reduction of collagen deposition, the obstruction of HSCs activation, the inactivation of angiogenic signaling pathways and the weakening of hepatic sinusoidal capillarization jointly confirmed that CFE might be promising to resist angiogenesis in liver fibrosis via the PDGFRB/ERK/HIF-1α and VEGFA/AKT/eNOS signaling pathways. Nevertheless, as a potential therapeutic drug, the deeper mechanism of Carthami flos still needs to be further elucidated.

Abstract
Premature ovarian failure refers to a series of symptoms of perimenopausal hot flashes, night sweats, decreased libido, vaginal dryness, insomnia, reduced menstruation, sparse hair, even amenorrhea, and even infertility before the age of 40 due to the decline of ovarian function. Premature ovarian failure is a common and difficult disease in gynecology. Its prevalence is increasing gradually, and the trend is younger. The aim of this experiment was to elucidate the role of human umbilical cord mesenchymal stem cells (HUCMSCs) in premature ovarian failure and its mechanism. HUCMSCs, KGN cells, and HEK293T cells were used in this experiment. Quantitative PCR and microarray analysis, ELISA inflammation and oxidative stress kits, RNA pull-down assay, luciferase reporter assay, proliferation assay, EDU staining, and Western blot analysis were used. In an in vitro model of premature ovarian failure, HUCMSCs attenuated inflammatory response, oxidative stress, and apoptosis. HUCMSCs ameliorated the premature ovarian failure model. The miR-100-5p expression was induced by HUCMSCs through methylation. miR-100-5p regulation influenced the role of HUCMSCs in an in vitro model of premature ovarian failure. HUCMSCs inhibited the in vitro expression of NOX4, NLRP3, and GSDMD proteins in the model. NOX4/NLRP3 signaling pathway affects the role of HUCMSCs in an in vitro model of premature ovarian failure through miR-100-5p. This experiment elucidated the role of HUCMSCs in premature ovarian failure and its mechanism, with a view to providing a clinical reference.
