Project Overview

This project focuses on stem cell engineering and differentiation into different types of muscle tissue (skeletal muscle, smooth muscle, and cardiac muscle) for transplant/regeneration. This research aims to address the social problem that many cases of muscle damage do not yet have good treatments; for example, patients with severe heart muscle damage often undergo invasive heart transplants and patients with skeletal muscle damage often go undiagnosed or untreated and the damage heals as scar tissue, often causing permanent pain or mobility limitations. On a scientific level, stem cells could not be induced to develop into functional muscle tissue until very recently, and there are still many problems with the approach that need to be dealt with in order for it to become a viable treatment for humans. These are the issues that our project seeks to address.

Background Information

This section is a work in progress.

Research Problem and Goals

Tissue engineering of mesenchymal stem cells and/or skeletal muscle-derived stem cells to induce differentiation into three major types of muscle tissue (skeletal muscle, smooth muscle, and cardiac muscle). Our goal is to narrow down the most effective methods to generate all types of muscle tissue in vitro, in order to lead to the development of strategies to repair injured muscle.

Project Details and Methods

Potential Societal Impact

Ideally the results of this study would identify the best methods for treating muscle damage of all types (cardiac, skeletal, and smooth) in vitro in order to improve therapies for these serious health problems. The impact of this study could potentially be quite large; the development of a treatment for regenerating heart muscle alone could potentially improve the conditions of the approximately one million Americans would have heart attacks every year and the impacts from techniques for other muscle types only add to the number of people who could be helped by this research.

This study focuses on the differentiation of ecto-MSCs in regenerating muscle tissue. EMSCs help in the formation of teeth, salivary glands, and muscle tissue in early development, and thus it was hypothesized that the transplantation of EMSCs might induce them to differentiate into mature skeletal muscle. It was discovered that EMSCs, in mice and therefore potentially in humans, can accumulate and form myotubes and continue differentiating into skeletal muscle when in a sheet of cells in vitro, so there is potential for cell therapy and engineering tissue that can repair skeletal muscle.

Molecular and Cellular Biochemistry. http://link.springer.com/article/10.1007%2Fs11010-007-9446-1

This study provided an analysis of how myogenic regulatory factors (MRFs), and specifically MyoD helps regulate skeletal muscle differentiation. NIH3T3 cell lines (embryonic mice fibroblasts) were transfected such that exogenous MyoD was expressed at high levels. When grown in vivo (in mice) and in vitro, the fibroblasts underwent myogenesis and remained stable, so it was concluded that MyoD may play an important role in cell-mediated gene therapy of skeletal muscle.

Journal of Cell Science. http://jcs.biologists.org/content/early/2014/04/13/jcs.134833.long

MSC differentiation toward smooth muscle cell (SMC) can be induced by some soluble factors, such as Transform Growth Factor beta 1 (TGF-β1) but is also influenced by adherent junctions. This study found that Cadherin-11 but not Cadherin-2 was necessary for MSC differentiation into SMC by influencing TGF-β receptor II pathway as well as a Rho-associated protein kinase pathway and inducing contractile function both in vitro and in vivo.

This study focused on using bone marrow derived MSCs and vectors that over express the fibroblast inducible factor 14 (Fn14) gene in order to see if they could induce differentiation into cells used in heart valves. It was found that the expression of α-smooth muscle actin (SMA) was significantly higher with Fn14, and the phenotype of these in vitro cells were similar to the phenotype of normal heart valves, so this may provide a therapeutic strategy for heart valve disease treatment.

International Journal of Tissue Engineering. http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3984572/#__ffn_sectitle

In this study, they experimented whether muscle differentiated from skeletal muscle derived stem cells (MDSCs) can express phenotypes (such as sarcomere proteins and transcription factors) shared between developing cardiac and skeletal muscle cells. They compared engineered muscle tissue derived from MDSCs to induced pluripotent stem cell-derived cardiac cells (iPS-EMT), and found that MDSCs can differentiate into muscle cells that mimic both developing cardiac and skeletal muscle which could possibly lead to therapeutic options of MDSCs in cardiac repair treatment.

Repairing injured skeletal muscle by cell therapy is a result of injected cells, but cell survival has typically been low. This study designed a degradable scaffold that can be implanted, in addition to the delivery of myoblasts and growth factors, that promoted the survival of cells in vivo and thus the functional regeneration of injured skeletal muscle.

Stem Cells Translational Medicine. http://stemcellstm.alphamedpress.org/content/early/2014/04/17/sctm.2013-0174.long

This study isolated skeletal muscle-derived interstitial progenitor cells and started to explore the potential of these cells for use in tissue engineering and muscle regeneration from a single multipotent stem cell type. They show that these cells can give rise to skeletal myoblast/myotubes, smooth muscle, and cardiomyocyte-like cells, which indicates that skeletal muscle (an easily accessible source) may be able to help regenerate other types of muscle tissue.

Induction of functional tissue-engineered skeletal muscle constructs by defined electrical stimulation. Scientific Reports. http://www.nature.com/srep/2014/140424/srep04781/full/srep04781.html

Because electrical impulses are necessary for skeletal muscle development in vivo, this study explored the idea of using electrical stimulation (and attempted to optimize a protocol) to fabricate functional skeletal muscle tissue in vitro, which may be used for therapies to restore damaged muscle.

This study describes the creation of biomimetic skeletal muscle tissues with phenotypes (structural/functional/myogenic properties) characteristic of native muscle tissue that also can be implanted in vivo for restoration. They also state that the implantation process is enhanced by formation of muscle architecture in vitro.

This study used human MSCs (retrieved from the bone marrow) and engrafted them in the myocardium of mice. The cells differentiated in cardiomycocytes (heart muscle cells) and expressed proteins (including those needed for contraction) levels similar to those of native cells. https://circ.ahajournals.org/content/105/1/93.full

The purified hMSCs from adult bone marrow engrafted in the myocardium appeared to differentiate into cardiomyocytes. The persistence of the engrafted hMSCs and their in situ differentiation in the heart may represent the basis for using these adult stem cells for cellular cardiomyoplasty

This paper summarizes the differentiation of skeletal muscle in normal development and native regeneration. In development, the upregulation of the transcriptional activators MyoD and Myf5 is required for the differentiation of stem cells into muscle cells. The proteins Myogenin, MRF4, myosin heavy chain (MHC), and muscle creatine kinase (MCK) are produced later in embryonic development and are necessary for viable muscle tissue. Of muscle regeneration, the paper identifies these key goals: regeneration of the myofibers, revascularization, reinnervation, and reconstitution of the extracellular matrix. The paper also identifies that after an injury, muscle first undergoes degeneration, which stimulates regeneration.
