Here, we present the free-living symbiotic flatworm Paracatenula galateia and its intracellular, sulfur-oxidizing bacteria as a system with previously undescribed strategies of bacteriocyte formation and bacterial symbiont transmission. Using thymidine analogue S-phase labeling and, we show that all somatic cells in adult worms - including bacteriocytes - originate exclusively from aposymbiotic stem cells (neoblasts).

Even in completely regenerated specimens there were many labelled . Irmeli Palmberg, Maria Reuter.

Even in completely regenerated specimens there were many labelled undifferentiated cells (. 20–45 h after exposure to T). I propose that neoblasts function both as stem cells for all differentiated cell types and as reserve cells with a determined life time. cle{tiationDA, title {Differentiation during asexual reproduction and regeneration in a microturbellarian}, author {Irmeli E.

Here, we present the free-living symbiotic flatworm Paracatenula galateia and its intracellular, sulfur-oxidizing bacteria as a system with previously undescribed strategies of bacteriocyte formation and bacterial symbiont transmission. We also provide morphological and immunohistochemical evidence that P. galateia reproduces by asexual fragmentation and regeneration (paratomy) and, thereby, vertically transmits numerous symbiont-containing bacteriocytes to its asexual progeny. Our data support the earlier reported hypothesis that the symbiont population is subjected to reduced bottleneck effects.
