The challenges and prospects of smooth muscle tissue engineering.

Many vascular disorders arise as a result of dysfunctional smooth muscle cells. Tissue engineering strategies have evolved as key approaches to generate functional vascular smooth muscle cells for use in cell-based precision and personalized regenerative medicine approaches. This article highlights some of the challenges that exist in the field and presents some of the prospects for translating research advancements into therapeutic modalities. The article emphasizes the need for better developing synergetic intracellular and extracellular cues in the processes to generate functional vascular smooth muscle cells from different stem cell sources for use in tissue engineering strategies.

This paper explores the potential of engineering smooth muscle tissues to treat vascular diseases, focusing on challenges like sourcing the right cells and creating supportive environments for cell growth. It highlights advances in materials that mimic the body's conditions and the use of 3D fabrication methods for creating complex structures. Additionally, it discusses the significance of mitochondrial function in blood vessel muscle cells. The research emphasizes interdisciplinary efforts and personalized treatments as key to developing effective therapies. The goal is to engineer lab-grown tissues that can repair or replace damaged blood vessels, offering hope for addressing major health challenges associated with vascular diseases.

Stem cell-based strategies for skeletal muscle tissue engineering.

Skeletal muscle tissue engineering has been a key area of focus over the years and has been of interest for developing regenerative strategies for injured or degenerative skeletal muscle tissue. Stem cells have gained increased attention as sources for developing skeletal muscle tissue for subsequent studies or potential treatments. Focus has been placed on understanding the molecular pathways that govern skeletal muscle formation in development to advance differentiation of stem cells towards skeletal muscle fates in vitro. Use of growth factors and transcription factors have long been the method for guiding skeletal muscle differentiation in vitro. However, further research in small molecule induced differentiation offers a xeno-free option that could result from use of animal derived factors.
