Renal pericytes: regulators of medullary blood flow [PDF]

, 2012
Regulation of medullary blood flow (MBF) is essential in maintaining normal kidney function. Blood flow to the medulla is supplied by the descending vasa recta (DVR), which arise from the efferent arterioles of juxtamedullary glomeruli.

AI–Guided 4D Printing of Carnivorous Plants–Inspired Microneedles for Accelerated Wound Healing

Advanced Materials, EarlyView.
This work presents an artificial intelligence (AI)‐guided 4D‐printed microneedle platform inspired by carnivorous plants for wound healing. A thermo‐responsive shape memory polymer enables body temperature–triggered self‐coiling for autonomous wound closure.

Ogerin induced activation of Gpr68 alters tendon healing

FASEB BioAdvances
Satisfactory outcomes after acute tendon injuries are hampered by a fibrotic healing response. As such, modulation of extracellular matrix deposition and remodeling represents an important intervention point to improve healing. During fibrosis, matrix is

Syndecan‐4 Protects the Heart From the Profibrotic Effects of Thrombin‐Cleaved Osteopontin

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2020
Background Pressure overload of the heart occurs in patients with hypertension or valvular stenosis and induces cardiac fibrosis because of excessive production of extracellular matrix by activated cardiac fibroblasts.

Extracellular matrix remodeling and TGF-β1/Smad signaling in diabetic colon mucosa [PDF]

, 2017
Diabetes is associated with metabolic and functional alterations in the gut. Using an experimental model of streptozotocin (STZ)-induced diabetes in rodents, we analyzed the extracellular matrix (ECM) and TGF-β/Smad signaling in the colon mucosa.

Biodegradable Carbonate Nanogels Loaded with Anti MFAP‐5 siRNA for Anti‐stromal Therapy of Hepatocellular Carcinoma

Advanced Science, EarlyView.
Polycarbonate nanogels enable lipid‐free delivery of anti‐MFAP‐5 siRNA into cancer‐associated fibroblasts (CAF) in hepatocellular carcinoma. In a cirrhotic murine model, this approach silences MFAP‐5, reduces fibroblast activation, and suppresses tumor growth by inhibiting NOTCH/Hes1‐driven angiogenesis. CAF‐targeted MFAP‐5 RNAi and conserved signaling

Cancer‐Associated Fibroblasts Functions as Multifunctional Architects of the Tumor Stroma and Represent Emerging Therapeutic Vulnerabilities

Advanced Science, EarlyView.
ABSTRACT Cancer‐associated fibroblasts (CAFs) are the predominant stromal components within the tumor microenvironment (TME), playing multifaceted roles in cancer progression through dynamic interactions with neoplastic and immune cells. Emerging evidence has revealed remarkable heterogeneity and plasticity of CAFs, which originate from diverse ...

Different distribution and density of myofibroblasts in idiopathic epiretinal membrane and epiretinal membrane in proliferative diabetic retinopathy

Scientific Reports
Myofibroblasts were recently identified as the most critical cells responsible for epiretinal membrane contraction, however the myofibroblast number in different types of membranes may differ substantially.

Promoting Treg Polarization‐Mediated Anti‐Scar and Appendage Regeneration in Wound Healing

Advanced Science, EarlyView.
This study develops a PLGA@LA‐BMP4‐PG bilayer scaffold to address scar formation and appendage loss in skin repair. The piezoelectric PLA layer enhances cell migration via electric fields, while GelMA delivers LA promoting Tregs polarization and BMP4 inhibiting FBs differentiation.

The Sonic Hedgehog Pathway Stimulates Prostate Tumor Growth by Paracrine Signaling and Recaptures Embryonic Gene Expression in Tumor Myofibroblasts [PDF]

, 2009
The Hedgehog (Hh) pathway contributes to prostate cancer growth and progression. The presence of robust Shh expression in both normal prostate and localized cancer challenged us to explain the unique growth promoting effect in cancer.
