“…Slow fibers develop very early in the trunk, from adaxial cells, and likely underlie movement of the trunk even before hatching (Devoto et al, 1996). Later-developing myogenic precursors in the dorsal and ventral myotome contribute to growth of the embryonic slow muscle fiber layer after its initial development (Barresi et al, 2001). Thus, even though trunk slow fibers derive from multiple sources, they attain the same superficial position.…”

“…Antibodies used were MF20, a mouse monoclonal antibody obtained from the Developmental Studies Hybridoma Bank (DSHB) that labels differentiated skeletal muscle cells in all species examined (Bader et al, 1982); S58, a mouse monoclonal antibody obtained from DSHB raised against chicken myosin (Crow and Stockdale, 1986) that labels slow muscle fibers in zebrafish (Devoto et al, 1996); zm4, an antibody that specifically labels fast fibers in zebrafish (Barresi et al, 2001) and Pax7, a mouse monoclonal antibody obtained from DSHB that specifically recognizes Pax7 protein in chicken (Kawakami et al, 1997). zm4 supernatant was purchased from the Zebrafish International Resource Center, which is supported by grant P40 RR12546 from the NIH-NCRR.…”

After initial patterning, muscle in the trunk and fins of teleosts grows extensively. Here, we describe muscle growth in zebrafish, with emphasis on the pectoral fin musculature. In the trunk, slow muscle fibers differentiate first. In contrast, slow muscle does not appear in the pectoral fin until the beginning of the juvenile period. Mosaic hyperplasia contributes to trunk muscle growth, and new fibers are apparent within the muscle as early as 6 mm standard length. In the pectoral fin muscle, mosaic hyperplasia is not evident at any examined stage. Instead, the predominant mode of hyperplasia is stratified. In larval pectoral fin muscle new fibers appear subjacent to the skin, and this correlates with the expression of myogenic genes such as muscle regulatory factors and Pax7. Our results suggest that regulation of fiber type development and muscle growth may differ in the pectoral fin and trunk. Developmental Dynamics 237: 307-315, 2008.

Muscle‐specific expression of the smyd1 gene is controlled by its 5.3‐kb promoter and 5′‐flanking sequence in zebrafish embryos

Zebrafish SmyD1 is a SET and MYND domain-containing protein that plays an important role in myofiber maturation and muscle contraction. SmyD1 is required for myofibril organization and sarcomere assembly during myofiber maturation. Whole-mount in situ hybridization revealed that smyd1 mRNAs are specifically expressed in skeletal and cardiac muscles in zebrafish embryos. However, it is unknown if smyd1 is expressed in other striated muscles, such as cranial and fin muscles, and moreover, the regulatory elements required for its muscle-specific expression. We report here the analyses of smyd1 expression using smyd1-gfp transgenic zebrafish. smyd1-gfp transgenic zebrafish were generated using the 5.3-kb smyd1 promoter and its 5-flanking sequence. GFP expression was found in the skeletal and cardiac muscles of smyd1-gfp transgenic embryos. GFP expression appeared stronger in slow muscles than fast muscles in transgenic zebrafish larvae. In addition, GFP expression was also detected in cranial and fin muscles of smyd1-gfp transgenic zebrafish larvae. In situ hybridization confirmed smyd1 mRNA expression in these tissues, suggesting that the expression of the smyd1-gfp transgene recapitulated that of the endogenous smyd1 gene. Deletion analysis revealed that the 0.5-kb sequence in the proximal promoter of smyd1 was essential for its muscle specificity. Together, these data indicate that smyd1 is specifically expressed in most, if not all, striated muscles, and the muscle specificity is controlled by the 5.3-kb promoter and flanking sequences.

“…There are two main models proposed for stratified growth: A) In zebrafish new slow and fast muscle fibres are first added at the end of the segmentation period from growth zones near the dorsal and ventral extremes of the myotome and close to the horizontal septum. This mode of muscle growth has been proven to continue into larval life, by traditional fibre size measurement, BruU labeling and in situ hybridisation (Barresi et al, 2001;Fernández, unpublished results, Fig. 3).…”

SUMMARY:The suborder Notothenioidei comprises 122 species divided into 8 families, with members of 6 of the families living outside Antarctic waters. The Antarctic species underwent an extensive radiation from a small demersal ancestor to occupy different ecological niches and levels in the water column. The axial muscle of Antarctic and some Subantarctic notothenioids is unusual in containing very large diameter muscle fibres and a low muscle fibre number. Maximum fibre diameters are greater than 500 µm in many species. There is no indication of systematic differences in fibre number, fibre type composition, ATPase activity, time of cessation of fibre recruitment (hyperplasia) and swimming performance between Antarctic and Subantarctic species. Instead, fibre number is significantly decreased in species belonging to the most derived families relative to the more basal families (a trend that also correlates with an increase in the diameter of the fibres). The length of the cell cycle of the muscle fibres shows cold compensation in the Antarctic species H. antarcticus relative to the closely related Subantarctic one (H. bispinis). Feeding after a starvation period results in a strong stimulation of the proliferation of muscle fiber progenitors in H. bispinis. Similar studies have not yet been performed on any Antarctic species.Keywords: Antarctic notothenioids, Subantarctic notothenioids, muscle development, muscle growth, temperature, hypertrophy, hyperplasia. RESUMEN: CRECIMIENTO MUSCULAR EN NOTOTÉNIDOS ANTÁRTICOS Y SUBANTÁRTICOS. -El suborden Notothenioidei comprende 122 especies divididas en 8 familias, incluyendo miembros de 6 de las familias que viven en aguas subantárticas. Las especies antárticas sufrieron una impresionante radiación a partir de un ancestro pequeño y demersal que les permitió ocupar diferentes nichos ecológicos y niveles en la columna de agua. El número total de fibras de la musculatura axial de nototénidos antárticos y algunos subantárticos es escaso y las fibras presentan un tamaño inusualmente grande, alcanzando diá-metros máximos mayores a 500 µm en muchas de las especies estudiadas. No existen diferencias sistemáticas entre la musculatura axial de nototénidos antárticos y subantárticos en el número de fibras musculares, los tipos de fibras musculares, la actividad ATPasa, el momento de cese de incorporación de fibras musculares (hiperplasia), ni en la capacidad (performance) natatoria a diferentes temperaturas. De hecho, el número de fibras musculares es significativamente menor en las especies pertenecientes a las familias más derivadas en comparación con especies de las familias más basales (una tendencia que también se correlaciona con un incremento en el diámetro de las fibras). La duración del ciclo celular muestra una compensación al frío en la especie antártica H. antarcticus en comparación con la especie subantártica más relacionada (H. bispinis). La alimentación luego de un período de ayuno produce una fuerte estimulación en la proliferación de progenitores de las fibras mus...
