Article Abstract
Expression of follicle-stimulation hormone receptor (FSHR) is confined to gonads and at low levels to some extragonadal tissues like human umbilical vein endothelial cells (HUVEC). FSH-FSHR signaling was shown to promote HUVEC angiogenesis and thereafter suggested to have an influential role in pregnancy. We revisited hereby the expression and functionality of FSHR in HUVECs angiogenesis, and were unable to reproduce the FSHR expression in human umbilical cord, HUVECs or immortalized HUVECs (HUV-ST). Positive controls as granulosa cells and HEK293 cells stably transfected with human FSHR cDNA expressed FSHR signal. In contrast to positive control VEGF, FSH treatment showed no effects on tube formation, nitric oxide production, wound healing or cell proliferation in HUVEC/HUV-ST. Thus, it remains open whether the FSH-FSHR activation has a direct regulatory role in the angiogenesis of HUVECs.

Objective: Adipose-derived regenerative cells (ADRCs) are promising cell sources for damaged tissue regeneration. The efficacy of therapeutic angiogenesis with ADRC implantation in patients with critical limb ischemia has been demonstrated in clinical studies. There are several possible mechanisms in this process such as cytokines and microRNA.

Vascularization of implanted biomaterials is critical to reconstructive surgery and tissue engineering. Ultimately, the goal is to promote a rapidly perfusable hierarchical microvasculature that persists with time and can meet underlying tissue needs. We have previously shown that using a microsurgical technique, termed micropuncture (MP), in combination with porous granular hydrogel scaffolds (GHS) fabricated via interlinking hydrogel microparticles (microgels) results in a rapidly perfusable patterned microvasculature.

Background: The roles of long non-coding RNAs (lncRNAs) in the progression of various human tumors have been extensively studied. However, their specific mechanisms and therapeutic potential in Triple-Negative Breast Cancer (TNBC) remain to be fully elucidated.
Materials And Methods: The qRT-PCR assay was utilized to assess the relative mRNA levels of TFAP2A-AS1, PHGDH, and miR-6892.

Defective wounds pose health risks, and treatment is challenging. Umbilical cord-derived mesenchymal stem cells (UCMSCs) show promise for healing. Primary UCMSCs were isolated and extracted in vitro, and the proliferation and differentiation characteristics were detected by flow cytometry and trilineage differentiation, and a 3D spherical cell culture was performed.

Reconstructing bone defects remains a significant challenge in clinical practice, driving the urgent need for advanced artificial grafts that simultaneously promote vascularization and osteogenesis. Addressing the critical trade-off between achieving high porosity/strength and effective bioactivity at safe ion doses, we incorporated strontium (Sr) into β-tricalcium phosphate (β-TCP) scaffolds with a triply periodic minimal surface (TPMS) structure using digital light processing (DLP)-based three-dimensional (3D) printing. Systematically screening Sr concentrations (0-10 mol%), we identified 10 mol% as optimal, leveraging the synergy between the biomimetic TPMS architecture, providing exceptional mechanical strength (up to 1.
