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

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 ...

Use of fluorescence in situ hybridization to detect and monitor transfected and amplified sequences in recombinant CHO cells

Florian Maria Wurm

Non-radioactive fluorescence in situ hybridization was used to detect transfected and amplified sequences in recombinant CHO cells. The cell lines used in this study are based on DHFR-deficient CHO-DUKX cells. The recombinant CHO cells contain and express, ...

Molecular and cytogenetic analysis of an interstitial 20p deletion associated with syndromic intrahepatic ductular hypoplasia (Alagille syndrome)

Friedrich Beermann

High-resolution chromosome analysis of a 19-year-old female proband with syndromic intrahepatic ductular hypoplasia (Alagille syndrome, AWS) revealed an interstitial deletion of chromosome 20p with breakpoints provisionally located in or close to p11.22 an ...

Metaphase chromosome structure. Involvement of topoisomerase II.

Thierry Laroche

SCI is a prominent, 170,000 Mr, non-histone protein of HeLa metaphase chromosomes. This protein binds DNA and was previously identified as one of the major structural components of the residual scaffold structure obtained by differential protein extraction ...

High susceptibility for diploidy in ovulated oocytes from XO mice

Friedrich Beermann

Adult female mice of the "sensitive" NMRI/Han strain ovulate diploid oocytes after gonadotropin treatment. Other mouse strains are "non-sensitive" with respect to the ovulation of such diploid oocytes. In this study we combined the impaired ovarian situati ...

Mechanisms of nondisjunction: facts and perspectives

Friedrich Beermann

An ordered segregation requires distinct processes of differentiation within the germ cell for recognition and segregation of homologous chromosomes/chromatids. These include synchronous maturation of the nucleus and cytoplasm, chromosome pairing and assem ...
