La cellule R1 des microfilaires (Nematoda), initiale du mésenchyme
Laboratoire de Zoologie (Vers) associé au C.N.R.S., Muséum National d’Histoire Naturelle (Pr A.-G. Chabaud), 57, rue Cuvier, F. 75 - Paris (5e) et Centre Muraz de Bobo-Dioulasso (Haute-Volta), France.
L’étude des premières heures du développement des microfilaires (essentiellement Setaria labiatopapillosa) chez l’hôte intermédiaire permet de préciser la fonction de certaines cellules particulières et l’origine de quelques organes : les cellules R2 à R4 servent à l’élaboration du rectum ; la cellule R1 est à l’origine de la musculature de la Filaire adulte ; l’intestin se forme à partir de 5 initiales visibles dès le début du développement ; l’œsophage se construit autour d’un axe cuticulaire qui s’étend de l’extrémité apicale jusqu’au voisinage du noyau intestinal le plus antérieur.
Abstract
The study of the first hours of development of Microfilaria (exclusively Setaria labiatopapillosa) in the intermediary host has unable the author to assess the fate of some peculiar cells and the origin of some organs. The R2 to R4 cells are involved in the production of the rectum. The R1 cell will give rise to the adult Filaria musculature. The intestine is formed by five initial cells which become apparent from the early stages of development. The oesophagus is fashioned round a cuticular axis extending from the apical end to the proximity of the most anterior intestinal nucleus.
