Brief Description of Main Results

1.    Basic research and development of new methods (approx. 16) in light and EM cytochemistry of cell nucleus.
2.    Studies of cell nucleus revealed co-operative character of levels of the chromatin organisation. In addition, discovered (1) Fractality of the rosette-like high level chromatin packaging (1989-1993); (2) Oscillatory character of the nuclear response  to damage stress (1990-1993).
3.    Staining properties of tumour cell chromatin were found associated with superhelicity of DNA.
4.    Transdifferentiation in development and induction of differentiation in tumours were shown to involve asymmetric cell  divisions and apoptosis.
5.    Aberrant cell cycle and cell death were found to have common features in embryonic development and tumours.
6.    Survival of the DNA damage-resistant tumours is likely due to the activation of the meiosis-like program in endopolyploid cells (1998- ).
