Induction and specification of the vertebrate ectodermal placodes: precursors of the cranial sensory organs.

abstract：BACKGROUND INFORMATION:Homotypic internalisation of tumour cells has frequently been observed in tumour tissue sections. Events of non-professional phagocytosis, however, may also occur in normal tissue if the number of dying cells exceeds the phagocytic capacity of professional phagocytes such as macrophages and dendr...
