title: [Internuclear chromosomal bridges and nuclei with protrusions in cellular populations of rat PA-23 rhabdomyosarcoma].
abstract: Internuclear chromosome bridges (CB) and nuclear protrusions (NP) were investigated in cell populations of RA-23 rat rhabdomyosarcoma. A morphological classification of different types of CB and NP has been offered. The obtained data suggest a morphological similarity between CB and NP. It is likely that NP could arise from CB after its break. So, NPs may be regarded as remains of broken CB.
