Abstract:
:Programmed cell death (PCD) via apoptosis is characterized by nuclear pyknosis and fragmentation, and biochemically by oligonucleosomal cleavage of DNA. Apoptosis occurs in the developing nervous system, whereas its role in neurodegenerative diseases is still debated. Recognition of apoptotic cells has recently been facilitated by in situ end-labeling (ISEL) techniques which identify DNA strand breaks through incorporation of labeled nucleotides. We have applied two ISEL assays to physiological and pathological conditions affecting the nervous system in which PCD is likely to occur. Terminal transferase assay was more sensitive than DNA polymerase assay and allowed the recognition of a larger number of cells than conventional histology. Apoptotic cells were readily found in the developing spinal cord and dorsal root ganglia. Medulloblastomas, gliomas, brain lymphomas and metastases showed abundant apoptotic cells either isolated or grouped in small foci. Labeling was also found in cells without a clearcut apoptotic morphology. Apoptotic cells were not found in Alzheimer's disease, amyotrophic lateral sclerosis and human and mouse prionic encephalopathies. Our results show that ISEL is a useful technique for demonstrating apoptotic cells in nervous tissue during development and in brain tumors. Lack of staining in neurodegenerative diseases suggests that other types of PCD might be involved.
