Border Cells (Drosophila) - Importance

Importance

This migration of the border cells appears to be important for two reasons – the formation of a structure called a micropyle, which is important for sperm entry, and for expressing the torso-like gene, which is an anterior-posterior patterning signal. Laser ablation of the border cells or their failure to migrate lead to improper morphogenesis of the micropyle.

Famous quotes containing the word importance:

    The child thinks of growing old as an almost obscene calamity, which for some mysterious reason will never happen to itself. All who have passed the age of thirty are joyless grotesques, endlessly fussing about things of no importance and staying alive without, so far as the child can see, having anything to live for. Only child life is real life.
    George Orwell (1903–1950)

    We have been told over and over about the importance of bonding to our children. Rarely do we hear about the skill of letting go, or, as one parent said, “that we raise our children to leave us.” Early childhood, as our kids gain skills and eagerly want some distance from us, is a time to build a kind of adult-child balance which permits both of us room.
    Joan Sheingold Ditzion (20th century)

    For even satire is a form of sympathy. It is the way our sympathy flows and recoils that really determines our lives. And here lies the vast importance of the novel, properly handled. It can inform and lead into new places our sympathy away in recoil from things gone dead. Therefore the novel, properly handled, can reveal the most secret places of life: for it is the passional secret places of life, above all, that the tide of sensitive awareness needs to ebb and flow, cleansing and freshening.
    —D.H. (David Herbert)
