Quarto, Natalina is a Senior Scientist in Dr. Longaker's laboratory. She received her PhD in Biological Sciences from the University of Napoli Federico II and Specialization in Medical Genetic from the University of Roma "La Sapienza". She pursued her postdoctoral research at the New York University with a focus on FGF-2 Biology. In her research, Natalina successfully identified for the first time that there are three forms of Fibroblasts Growth Factor-2 (FGF-2), namely high molecular weight (HMW-FGF-2) and low molecular weight (LMW-FGF-2) with different sub cellular distribution and functions. She was able to unveil and define how these forms promote distinct biological outcomes. She then continued her research on FGF-2 signaling pathways at the University of Paul Sabatier in Toulouse, France.

After that, Natalina spent 3 years among the University of California in San Francisco (UCSF) and the Rockefeller University in New York where she dedicated her research time to cloning tissue-PA and LTBP1 genes from Xenopus and performing functional studies using this organism.

In 2000, she moved from New York alongside Dr. Michael Longaker to join him in his new laboratory at Stanford University. Since then, her major scientific interest is centered on skeletal biology and regenerative medicine. 

One of her main research interests focuses extensively on calvarial bones of different embryonic tissue origin, 

and on how different tissue origin impacts the osteogenic potential and skeletal repair of these bones.


This investigation focuses on the neural-crest derived frontal bone and paraxial-mesoderm derived parietal bone. It has unveiled significant and substantial differences between the two parietal bones highlighting a key molecular mechanism(s) responsible for the different osteogenic capacity and tissue repair observed between the two bones.

A second area of research is centered on the development and patterning of cranial sutures, specifically the posterior frontal (PF) suture (metopic in humans) - a fusing suture. She has identified the timing and process through which the PF suture closes demonstrating two things: this suture fuses through an endochondral ossification process, and that canonical Wnt signaling is a major player in controlling the patency of cranial sutures. Natalina's current major focus is to understand the molecular mechanism(s) underlying the premature closure of a suture, namely craniosynostosis. Current research on this topic is revealing novel bio-molecular aspects of the craniosynostosis which suggest that this pathological condition is an outcome of unbalance in stem and progenitor populations.

On her free time, Natalina enjoys sailing and growing orchids.
