Transformation of external sensilla to chordotonal sensilla in the cut mutant of Drosophila assessed by single-cell marking in the embryo and larva.

abstract：:Basement membranes (BMs) were first described in the mid-19th century, but they were not isolated and prepared for compositional studies until nearly 100 years later. Early methods of isolation were carried out on renal glomeruli, which were first sub-fractionated from kidney tissues by sieving. BMs were then isolated...
