floor cell [FBbt_00046037]

A dorsal appendage forming follicle cell that forms the floor of the cellular tube encircling the developing dorsal appendages. These cells are initially located in two bilaterally symmetric domains in the dorso-anterior of the oocyte associated follicular epithelium, located immediately posterior to the centripetally migrating follicle cells and lateral of the dorsal midline. Each domain consists of a single cell width arc that borders the roof cell domain on its anterior and dorsal sides. During elongation and sealing of the dorsal appendage forming cellular tube, the two sides of each floor cell domain extend beneath the roof cells and meet to form a seam.
