Description
| - Účelem studie byl morfologický popis časného postnatálního růstu iniciálních lymfatických cév ve ventrálním pruhu m. spinotrapezius krysy. Elektronmikroskopicky nebyly ve svalech novorozených krys prokázány dobře vyvinuté lymfatické cévy. Nápadná byla pouze přítomnost specificky tvarově polarizovaných mesenchymálních buněk vtěsném sousedství centrálnícvh krevních cév. Ve svalech jednodenníchaž dvoutýdenních zvířat se tyto buňky postupně spojovaly formou jednoduchých mezibuněčných spojů a vytvářely základy nekompletní lymfatických lumin. Ta byla morfologicky velmi dobře oddělena od okolního svalového intersticia. Ve svalech třítýdenních krys již byla iniciální lymfatická lumina velmi dobře vyvinuta, včetně jemných chlopní, a jejich endotelové buňky prokazovaly slabou pinocytotickou aktivitu a absenci basální laminy. Vrostoucích lymfatických endoteliích nebyly nalezeny známky mitotické aktivity ani známky pučení, typického pro rostoucí krevní kapiláry. (cs)
- The aim of this study was the morphological description of the early postnatal growth of initial lymphatics in the ventral stripe of the spinotrapezius muscle of the rat. Electron-microscopically it was found that in the muscles of newborn rats no well-developed lymphatics were apparent, but the presence of specifically polarized mesenchymal cells in the close vicinity of central blood vessels was evident. In animals aged one-day through two-week-old, those modified mesenchymal cells continuously joined with one another, to form simple intercellular contacts and incomplete lymphatic lumina. Morphologically, they were well demarcated relative to the surrounding muscular interstitium. In three-week-old rats, all intramuscular lymphatics were well developed, including fine intraluminal valves, and their endothelial cells presented slight pinocytotic activity and a complete absence of a basal lamina.
