punt and schnurri regulate a somatically derived signal that restricts proliferation of committed progenitors in the germline

To identify regulators of stem cell lineages, we are focusing on spermatogenesis in Drosophila. In spermatogenesis, each germline stem cell divides asymmetrically, renewing itself and producing a transiently amplifying daughter, which divides four times. B ...

bag-of-marbles and benign gonial cell neoplasm act in the germline to restrict proliferation during Drosophila spermatogenesis

Pierre Gönczy

Stem cells divide asymmetrically, regenerating a parental stem cell and giving rise to a daughter cell with a distinct fate. In many stem cell lineages, this daughter cell undergoes several amplificatory mitoses, thus generating more cells that embark on t ...

The regeneration of the cephalic neural crest, a problem revisited: the regenerating cells originate from the contralateral or from the anterior and posterior neural fold

Anne Grapin-Botton

The mesencephalic and rhombencephalic levels of origin of the hypobranchial skeleton (lower jaw and hyoid bone) within the neural fold have been determined at the 5-somite stage with a resolution corresponding to each single rhombomere, by means of the qua ...

Maternal inheritance of P cytotype in Drosophila melanogaster: a "pre-P cytotype" is strictly extra-chromosomally transmitted

Bruno Lemaitre

In Drosophila melanogaster, transposition of the P element is under the control of a cellular state known as cytotype. The P cytotype represses P transposition whereas the M cytotype is permissive for transposition. In the long-term, the P cytotype is dete ...

Tissue preference and differentiation of malignant rat x mouse hybrid cells in chimaeric mouse fetuses

Denis Duboule

Mouse teratocarcinoma cells (OTT6050) deficient for thymidine kinase were fused with rat hepatoma cells ( Fu5AH ) deficient for hypoxanthine phosphoribosyltransferase using inactivated Sendai virus. The hybrid cells were selected and cultured in the presen ...

Islet Transplantation in Mice Differing in the I and S Subregions of the H-2 Complex

Steinunn Baekkeskov Hanahan

Pancreatic islets from A.TH mice were transplanted into the spleen or streptozotocin (SZ)-diabetic A.TL mice. The two strains of mice are congenic inbred strains, differing only in the I and S subregions of the H-2 complex. The allogeneic islet grafts decr ...
