A variety of cell types develop when cells of 6 1/2-8 1/2 h Drosophila embryos are cultured in an improved medium. Nerve, muscles, fat-body, chitin-secreting, and macrophage-like cells (possibly haemocytes) appear in the first 24 h and mature over the next week.

For the first time haematological studies on freshwater crab P. masoniana (Henderson) has been carried out in Jammu, India. The aim of studies were to determine various type of hemocytes, their total and differential count as well. Based on morphological studies of hemocytes under microscope three types of haemocytes were identified viz., Hyalinocytes (H), Semigranulocytes (SG) and Granulocytes...
