Sharing NYSCF's Voice on Big Data, Precision Medicine and Innovative Business Models
Sharing NYSCF's Voice on Big Data, Precision Medicine and Innovative Business Models
NYSCF CEO Susan L. Solomon discussed "Harnessing patient data using stem cells to power precision medicine" during her co-located keynote plenary talk at the Cord Blood World Europe, World Advanced Therapies & Regenerative Medicine Congress 2017, and the World Precision Medicine Congress 2017 conferences in London, UK. Following the plenary discussion, Ms. Solomon joined a panel to explore "The Future of Medicine: A Conversation" with Dr. Ian Campbell, Director for Health and Life Sciences, Innovate UK; Dr. Joanne Kurtzberg, Director, Carolinas Cord Blood Bank, Duke University; and Dr. Patrick Keohane, Chief Medical Officer, BenevolentAI.
 
The annual New York BIO conference in Manhattan also featured Ms. Solomon on a panel exploring the success of "Research Foundations with Innovative Business Models in New York" alongside Annette Bakker of the Children's Tumor Foundation, Michael Batten of the T1D Fund and JDRF, Sohini Chowdhury of The Michael J. Fox Foundation for Parkinson’s Research, Lara Sullivan of Pfizer, and the New York City Economic Development Corporation.
 
 
 
NYSCF Innovator Maps Neural Circuit for Fly Navigation
NYSCF Innovator Maps Neural Circuit for Fly Navigation

To successfully exist, many animals keep track of their angular heading, or directionality, over time as they navigate their environments; however, the brain architecture enabling this capability has never been mapped in any species until now. Using a fly animal model, NYSCF – Robertson Neuroscience Investigator Alumnus Dr. Gaby Maimon and a team at The Rockefeller University successfully mapped two classes of shifting neurons, clockwise- and anticlockwise-shifting, each with two subtypes, whose wiring and physiology provide a means to rotate an angular heading estimate based on the fly’s angular velocity.

Importantly, the features of this biological circuit are similar to proposed computation models of head-direction cells in rodents. Therefore, this research may shed light on neural systems integration in a wide variety of species.

NYSCF Innovator Improves Neuron Derivation from Stem Cells
NYSCF Innovator Improves Neuron Derivation from Stem Cells

Creating consistent groups of mature neurons from stem cells remains challenging in the lab. NYSCF – Robertson Stem Cell Investigator and NYSCF – Robertson Stem Cell Prize recipient Dr. Marius Wernig and his team from Stanford University developed a method to consistently derive GABAergic neurons directly from human stem cells with high levels of maturity. The scientists used lineage-specific transcription factor programming to achieve these remarkable results. 

Published in Nature Methods, this work represents an important step towards enabling the study of diseases affecting these neurons and their signaling ability.

NYSCF Innovator Develops Mature, Diverse Brain "Organoids"
NYSCF Innovator Develops Mature, Diverse Brain
NYSCF – Robertson Stem Cell Investigator Dr. Paola Arlotta and a team of researchers at Harvard University developed protocols to create human brain organoids, organ models cultured from induced pluripotent stem cells, capable of growing and maturing to an unprecedented level. Typical organoids are developed and tested in a matter of weeks. The organoids, reported in Nature, were cultured and matured for nine months or longer.
 
The scientists analyzed gene expression in more than 80,000 cells taken from 31 brain organoids and compared the results to those documented from human brain tissue samples to identify the multitude of different brain cell types displayed in the organoids. These organoids also developed key traits such as spontaneously active neural networks, dendritic spines and light-sensitive cells. 
 
These human brain models enable a next-level platform for neuropsychiatric disease modeling and drug discovery.
 
NYSCF – Robertson Neuroscience Investigator Dr. Ed Boyden of MIT Media Lab was also an author on the paper.

NYSCF Innovator Improves Revolutionary Imaging Technique
NYSCF Innovator Improves Revolutionary Imaging Technique

NYSCF – Robertson Neuroscience Investigator Dr. Ed Boyden and his team at MIT Media Lab published their latest work advancing and improving their revolutionary imaging technique: expansion microscopy. The research, published in Nature Methods, describes an advance on standard expansion microscopy, increasing magnification by 20x the sample size. 

The expansion microscopy technique revolutionized imaging by physically expanding biological specimens while maintaining their characteristics and proportions. Standard expansion microscopy begins by embedding and homogenizing a specimen in a dense polymer gel. The specimen is then physically expanded by 4.5x its starting size by swelling the gel. This technique enables scientists to study the biological structures of minute specimens with unheard of clarity, using standard microscopes and magnification. 

The new process, dubbed iterative expansion microscopy, puts the sample through an additional expansion enabling nanometer resolution imaging of cells and tissues on conventional microscopes.
