    Notes: Abstract Using immunocytochemistry, electrophoresis and immunoblotting, we studied the expression of fast and slow myosin heavy chain isoforms in adult ferret muscles during quiescent and breeding periods. Adult cremaster muscle expressed slow and fast myosin heavy chain in relatively similar amounts during the quiescent period. During the breeding period, the expression of slow myosin heavy chain I, significantly decreased, and fast myosin heavy chain II, was predominant. No alteration of the MHC pattern in EDL and soleus muscles was detected between the quiescent and breeding periods. The possible involvement of androgens and mechanical factors in the regulation of myosin heavy chain expression in adult cremaster muscle is discussed.

    Origin and development of VIP and substance P containing neurons in the embryonic avian gut (1981)

    Notes: Summary The development of substance P (SP) and VIP containing structures of the quail and chick guts was studied by immunocytochemistry. The appearance of VIP and substance P nerves follows a rostrocaudal pattern from day 9 in the quail and day 10 in the chick embryo. Immunoreactive fibres are first visible in the oesophagus and at 12 days they extend over the whole length of the intestine. VIP and substance P ganglionic cells are first localized in the foregut (day 9 for VIP containing neurons and day 13 for SP ones) and observed in the mid- and hind-gut just before hatching. Transplantation on the chorioallantoic membrane (CAM) of fragments of various parts of the digestive tract were carried out to see whether in such circumstances the pattern of VIP and SP containing nerves was comparable to normal. The explants contained numerous SP and VIP immunofluorescent nerve fibres. In addition, cell bodies with VIP and SP immunoreactivity appeared brightly fluorescent in the enteric ganglia of the graft showing that these peptidergic nerve cells belong to the intrinsic innervation of the gut.

    Desmin-lacZ transgene expression and regeneration within skeletal muscle transplants (1997)

    Notes: Abstract The purpose of this study was to investigate the initiation and time course of the regeneration process in fragments of skeletal muscle transplants as a function of muscle tissue age at implantation. The appearance of desmin occurs at the very beginning of myogenesis. The transgenic desminnls lacZ mice used in the study bear a transgene in which the 1 kb DNA 5′ regulatory sequence of the desmin gene is linked to a reporter gene coding for Escherichia coliβ-galactosidase. The desmin lacZ transgene labels muscle cells in which the desmin synthesis programme has commenced. We implanted pectoralis muscle fragments from fetal transgenic embryos and mature and old transgenic mice into mature non-transgenic mice. Early events of myogenesis occurring during regeneration started sooner in transplants from 4-month-old (day 3 post-implantation) muscle than in those from 24-month-old (day 5-6 post-implantation) muscle, and they lasted longer in those from young (day 17 post-implantation) than in those from old (day 14 post-implantation) muscle fragments. In adult muscle, transgene activation proceeded from the periphery toward the centre of the transplant. In transplants from fetal 18-day-old pectoralis, myotubes with transgene activity were observed from day 1 to day 19. Desmin immunoreactivity, which appeared about one day after transgene activation, was followed by myosin expression. In adult transplants, the continuity of laminin labelling was disrupted around degenerative fibres, illustrating alteration of the extracellular matrix. Our data suggest that satellite cells from old muscle tissue have lower proliferative capacity and/or less access to trophic substances released by the host (damaged fibres, vascularization) than those from fetal or young adult muscle

    Comparative analysis of satellite cell properties in heavy- and lightweight strains of turkey (1998)

    Notes: Abstract The growth of muscle during postnatal development results partly from the proliferation of satellite cells and their fusion with muscle fibres. We analysed the properties of satellite cells in a heavyweight (HW) turkey strain characterized by high body weight and a fast growth rate, and in a lightweight farm strain (LW) characterized by low body weight and a slow growth rate. Satellite cell activation was then examined in stretched-overloaded anterior latissimus dorsi (ALD) muscle by weighting one wing in young turkeys from both strains. As early as day 1 of stretching for HW and day 2 for LW, small embryonic-like fibres expressing ventricular cardiac myosin heavy chain (MHC) isoform were observed. Following four days of stretching, the number of nascent fibres had increased in both strains but was significantly greater in HW than LW ALD muscle. The proliferation and differentiation capacities of satellite cells from HW and LW strains were investigated in culture. As judged by in vitro measurements of 3H-thymidine incorporation and DNA content, satellite cells of HW turkey exhibited a greater proliferative capability than those of LW turkey. No differences in the temporal appearance of muscle markers (desmin, MHC isoforms) were noted in vitro between the two strains. These data confirm our in vivo observations indicating that selection based on growth rate does not modify muscle fibre maturation. Our in vivo and in vitro observations suggest that variations in the postnatal muscle growth pattern between HW and LW strains may be related to a difference in the capacity of their satellite cells to proliferate.

    Do neural crest cells in the pancreas differentiate into somatostatin-containing cells? (1980)

    Notes: Summary The possibility that the somatostatin cells are derived from the neurectoderm has been questioned in avian embryos. Isotopic and isochronic transplantations of the neural primordium from quail into chick embryos were made at the vagal level (somites 1 to 7). Quail and chick cells can be distinguished by the structure of their nucleus. The somatostatin cells were characterized immunocytochemically. In no case did quail cells showing the immunological reaction originate from the neural crest.
