3T3 mouse fibroblasts responded differently to specific near‐infered signals than epithelial CV1 cell. Furthermore, signals with the same wavelength and energy changed the percentages of attracted and repelled 3T3 cells if their intensity modulation was altered. I found this result in a 22 month long study which established a spectrum of motile responses of 781 individual 3T3 cells and 148 CV1 cells to the near‐infrared emissions of microscopic, pulsating light sources using the infrared spot‐irradiation phase‐contrast (IRSIP) microscopic [Albrecht‐Buehler, 1991: J. Cell Biol. 114:493–502]. Thus the response of cultured, mammalian cells to near‐infrared light signals is not merely a matter of total energy absorption by cirtain cytoplasmic componets. Since it seems to depend on the cell type and the temporal pattern in which the light energy is emitted, it appears to imply the existence of a new kind of cellular information. © 1995 Wiley‐Liss, Inc.
