30th June 2026 Newsletter
Hi guys. This is the eighteenth newsletter from the Rejuvenation Science Institute (ICR). In these newsletters, we will tell you what we've done, since the last newsletter, to accelerate the development of rejuvenation science.
The ICR is setting up its own laboratory to support the rejuvenation experiments

During the month of June 2026, the ICR made progress in setting up its own laboratory, which will have the materials, equipment, and personnel necessary to carry out activities in support of rejuvenation experiments. We are also in the process of establishing an agreement for the provision of animal facility services, where we will be able to test the compounds produced in our laboratory on rodents, thereby drawing on the expertise of veterinarians specializing in preclinical testing.
These new initiatives will complement the experiment conducted with the university Unicamp, in which we will test the new dose on rats in November 2026, replicating Harold Katcher’s seminal rat rejuvenation experiment. Preparations for the mouse rejuvenation experiment have also begun, and we hope to have some very important news to share with you about this in the coming months.
Interview with Dr. Priscila Chiavellini, a specialist in partial reprogramming
The president of the ICR, Nicolás Cherñavsky, conducted an interview with Dr. Priscila Chiavellini for the YouTube channel of Heales, one of the ICR’s leading donor organizations. Dr. Priscila Chiavellini co-authored Harold Katcher’s 2023 article in the journal Geroscience while working in Dr. Rodolfo Goya’s laboratory at the University of La Plata (Argentina). Currently, Dr. Chiavellini is a postdoctoral researcher in Professor Vittorio Sebastiano’s laboratory at the University of California, Irvine. Professor Sebastiano is a pioneer in studies of partial reprogramming for the rejuvenation of human cells. The interview, conducted in Spanish, discusses Dr. Chiavellini’s current and past research topics: partial cellular reprogramming, young plasma therapies, and ovum rejuvenation.

This is a collective effort
This experiment is a collective effort to reproduce Harold Katcher's seminal study, in which the ICR relies on the contribution of those interested in the realization of the experiment. Thus, if you know someone who might be interested in the content of this newsletter, you can forward it to them. Also, if you are not yet a financial contributor of the ICR, we invite you to become one by clicking on this link.
So that's it. We're carrying on, and we won't rest until we've implemented rejuvenation in human beings. See you next time!
