, 1994
length and capillary curvature of rat hindlimb muscles in vivo. J. Appl. Physiol. 78(6): 2047-2051,1995.-Mammalian skeletal muscle fibers have been reported to develop maximum force at a sarcomere length (L,) of -2.5 pm.

Cardiac sarcomere structure is maintained by a balance between sarcomere protein synthesis and degradation.

, 2012
We postulate that GATA4 regulates CARP expression and both act to induce sarcomere gene transcription. CARP expression is subject to a negative feedback regulatory mechanism.

Chamber‐Specific Decellularized Extracellular Matrices Differentially Modulate Cardiomyocyte Subtypes to Drive Engineered Heart Tissue Development and Function

Advanced Healthcare Materials, EarlyView.
Chamber‐specific decellularized extracellular matrices (ECMs) were developed, preserving native proteomic profiles of ventricular and atrial myocardium. These innate biochemical cues differentially modulate cardiomyocyte subtypes to drive engineered heart tissue development and function, highlighting the importance of incorporating regional ECM cues in

An optimized approach to study nanoscale sarcomere structure utilizing super-resolution microscopy with nanobodies.

PLoS ONE
The sarcomere is the fundamental contractile unit in skeletal muscle, and the regularity of its structure is critical for function. Emerging data demonstrates that nanoscale changes to the regularity of sarcomere structure can affect the overall function

Sarcomeric TPM3α in developing chicken [PDF]

Cytoskeleton, 2017
AbstractCloning and sequencing of various tropomyosin isoforms expressed in chickens have been described since the early 1980s. However, to the best of our knowledge, this is the first report on the molecular characterization and the expression of the sarcomeric isoform of the TPM3 gene in cardiac and skeletal muscles from developing as well as adult ...

Coaxially Electrospun Myocardial dECM‐ Based Nanofibrous Scaffolds Demonstrate Enhanced Cardiomyocyte Biocompatibility

Advanced Healthcare Materials, EarlyView.
Our coaxial electrospinning system is capable of incorporating decellularized myocardial extracellular matrix in a core‐sheath configuration, creating nanofibrous scaffolds. These scaffolds, in turn, support the maintenance of functional cardiomyocytes adhered to the surface of these bioactive scaffolds.

Multidimensional Cellular Micro‐Compartments to Model Invasive Lobular Carcinoma Dormancy

Advanced Healthcare Materials, EarlyView.
Invasive lobular carcinoma (ILC) is an understudied subtype of breast cancer that is susceptible to late recurrences. In this study, micro‐compartmentalization techniques spanning multiple dimensions, including 2D, pseudo‐3D, and 3D, are integrated to uncover the mechanisms underlying ILC dormancy, revealing the central role of p27Kip1.
