Epilogue as prologue. The skin: continual source of biologic problems and discoveries.

In much the same way as the survival of many species depends upon their abundant production of such genetic materials as pollens and spermatozoa, so does scientific progress depend upon a continual, lavish production of basic scientific works. In stimulating assembling, and disseminating various scientific studies related to the skin, the Montagna Symposia on the Biology of Skin have ensured progress not only in the understanding and management of skin was, is, and probably will always will be one of the richest sources of basic biologic information. No scientific discovery is wasted, no accurate clinical observation useless. No one can foresee when or how some seemingly irrelevant discovery in pure science or some seemingly insignificant clinical observation will yield fruits of incalculable practicable value. We cite here a few examples of some of the best results from apparently unrelated research and isolated clinical findings. In dermatologic research, the circular rhythm from patient with cutaneous disease to laboratory and from laboratory back to patient creates a centrifugal force that often spins off valuable discoveries.
