To understand aging, as felt by persons, studied by medical science through age-related diseases, is an ancient preoccupation of humanity and research. In order to understand its multiple facets, the traditional “method” of experimental medicine, model experiments are of crucial importance. This was largely facilitated when cell-tissue culture methods were developed. Current methods for cell-tissue cultures were developed only during the second part of the 20th century, with the exception of some earlier attempts we shall shortly mention. Early studies were carried out by Alexis Carrel, a French surgeon from Lyon who worked during most of his carrier at the Rockefeller Institute in New York City. He used explant cultures of chicken embryos, maintained in a nutritional medium containing blood plasma and chick embryo extracts, obtained by grinding young chick embryos and using the filtrate of this tissue suspension. He showed that chick embryo heart explants could continue to beat, and muscle explants could contract upon stimulation, for a long time.Interested in aging, Carrel noticed that such explant cultures could be kept in sterile conditions at 37 C for much longer than the life expectancy of the animal. He concluded that disease and death are mainly due to body-fluids,“humors” which would progressively alter with age and harm the organism. Carrel was successfully contradicted in the nineteen sixties when Len Hayflick made his important observations on cell cultures and showed that normal, non-transformed cells cannot divide indefinitely. Hayflick’s findings were not immediately accepted. He investigated closely Carrel’s methodology and even interviewed a former technician of Carrel, retired in the “colonies”. She told Hayflick that the embryo extract had to be prepared in Lyon and delivered by airplane to Carrel’s lab in New York. As it was filtered during its preparation using a tissue (gauze), it could contain fresh living cells that thus could explain the apparently illimited survival of the cultures. Other scientists who attempted to reproduce Carrel’s findings, invariably failed and Hayflick’s paradigm was progressively accepted, not however without repeated denials and criticisms. Most scientists who worked according to the guidelines published by Hayflick could reproduce his results. During the 2nd part of the last century cell-and tissue culture methods became standardized, and culture dishes and media became commercially available. This largely contributed to the inter-laboratory standardization of culture-methodology and settled to a
