The LEO Foundation is excited to reveal the winner of the LEO Foundation Award 2019, Region Americas – Maksim Plikus.
Maksim Plikus is Associate Professor at the Department of Developmental and Cell Biology, School of Biological Sciences, University of California, Irvine, USA. He receives 100,000 USD for his research in skin stem cells and regeneration.
The LEO Foundation Award 2019 has just been presented by The LEO Foundation Chief Grant Officer, Ida Brams, at a ceremony at the SID Annual Meeting in Chicago.
“I’m very proud to present the LEO Foundation Award 2019 Region Americas to Maksim Plikus,” Ida Brams smiles. “He is such a brilliant researcher and a great storyteller – congrats Max!”
A major direction of Maksim Plikus’s reseasrch aims to understand how skin uses selforganization to efficiently manage its stem cells. Among other things, he has discovered that thousands of hair follicles rely on distant signal-producing cells to coordinate their collective regeneration over the entire skin.
“Indeed, I am very excited and honored to be the recipient of this prestigious LEO Foundation Award,” says Maksim Plikus.
The Global Review panel was very excited about Maksim Plikus and said among other things:
“Max has innovative research ideas and the scientific results obtained from his work have significant translational value”
“Max’s research is highly original and shows incredible vision – and his work is already having a major impact on dermatology”
“Max’s research challenges paradigms and he shows potential to become a leader in the field”
“Max’s work is highly innovative, exploring new frontiers with high-risk high-reward ideas – and his future career will be incredible”

About the award
Portrait of Maksim Plikus and his skin research – The exciting hair biology
“Skin is a very large and diverse organ with many regional differences and repetitive elements, such as hair follicles. It is very much like a complex landscape,” explains Maksim Plikus.
“To truly understand how skin works, it is not sufficient to just study its small parts. Simultaneously studying behaviors of its many parts is important. My research aims at that,” says Maks, who is focusing on cyclic growth of hair follicles. He finds hair biology very exciting:
“I study how thousands of hair follicles coordinate their growth activities with one another. Hair follicles actively communicate with one another and the decision to either grow or remain dormant is achieved by each hair follicle based on the cumulative long-range signaling input they receive from all their neighbors.”
Signaling crosstalk that hair follicles engage in is not limited to other hair follicles, but also includes non-hair follicle cell types. Prominently, hair follicles share signaling and co-regulate each other’s activities with skin adipose tissue.
Recently, Maksim Plikus showed that hair follicles in the center of early scar tissue can signal to fibroblasts and induce their conversion into fat cells. As the result, new adipose tissue can regenerate within scars.
What is unique about it?
“The scale at which we study skin – across large distances, and even across the entire skin – is fairly unique to our research,” explains Maks and continues:
“In our studies we actively incorporate mathematical modelling approaches. Large-scale skin phenomena that we study often have to do with patterns, and computational approaches are particularly well-suited for studying pattern-formation. We use mathematical models to predict candidate mechanisms of pattern-forming phenomena. We then use these predictions and test them experimentally.”
Such interdisciplinary approach can be highly successful as the tool for scientific exploration, and the Plikus group actively employ it in a number of both past and present projects.
The skin is a fantastic model
Situated at the interface with the external environment, skin has evolved to have robust regenerative responses to be able to efficiently repair itself.
“For this reason,” Maks says, “the skin is a fantastic model system for studying natural limits of tissue regeneration and for identifying regeneration promoting mechanisms,” and proclaims:
“Discoveries made in skin can ultimately be translated to organs, where regenerative responses are less efficient.”
Where can the research of Maksim Plikus lead to?
Regenerative responses can lead to novel strategies for the Regenerative Medicine, the ones that are based on enhancing endogenous regeneration-stimulating mechanisms within tissues and organs.
“Endogenous regenerative abilities of human skin are limited as compared to other animal model organisms and, often, insufficient to achieve complete healing,” says Maksim Plikus and continues:
“New regeneration-promoting signals that our research aims to identify in model organisms can potentially be translatable to humans. For instance, our work on skin wound healing promises new strategies for regenerating adipose tissue in scars, which clinically is a highly desirable outcome.
Maksim Plikus has always been inspired by nature as well as the classic scientific literature. But his fascination of the skin biology came by working in the laboratories of two leading scientists in the field:
“I had the honor of working with Dr. Cheng-Ming Chuong and Dr. George Cotsarelis. Both of them made significant and impactful discoveries in Developmental and Stem Cell Biology of the skin,” tells Maks.
“In both labs, I was given an opportunity to develop projects that were based on very novel and fascinating observations, that could not be explained with conventional knowledge at the time. Working on these projects opened my eyes to many other fascinating aspects of skin biology that still await answers”.
Lemonade and paddleboard
When Maks is not looking for new answers in skin biology, he does enjoy other aspects of nature.
“Living close to the Pacific Ocean, some of my most favorite activities are open-water diving and stand-up paddle boarding. On a good day, you are almost guaranteed to encounter a pod of dolphins or seals while padding,” he smiles.
What also makes him smile, is his two-year old daughter who is already very helpful watering the household’s two orange trees and a lemon tree.
“While we can make lemonades year round, orange season is however only in the winter months.”
