NIBIB grantee Gordana Vunjak-Novakovic at Columbia Engineering announced in the journal Proceedings of the Naitonal Academy of Sciences that they have successfully grown fully functional human cartilage in vitro from human stem cells derived from fat tissue. Their study demonstrates new ways to better mimic the enormous complexity of tissue development, regeneration, and disease. Read the full press release at engineering.columbia.edu.
Roughly 6 million people in the United States live with some form of paralysis, most commonly resulting from stroke, spinal cord injury, or multiple sclerosis.1 This paralysis may affect one or both legs, one half of the body, or almost the entire body—both arms, both legs, and the torso. Some people experience temporary paralysis while for others it is permanent. Some also lose feeling in affected limbs.
The NIH Director's Blog profiles NIBIB grantee Jonathan Lovell at the State Univesrity of New York at Buffalo on his work to deliver chemotherapeutic drugs directly to tumors buy using a combination of nanoballoons and lasers. Read more at directorsblog.nih.gov.
NIBIB grantees David Beebe and Eric Karl-Heinz Sackmann at the University of Wisconsin-Madison have developed a cheap microfluidic device that can quickly diagnose asthma from a drop of blood, even if the person isn't showing symptoms. Read the full press release at news.wisc.edu.
Funded in part by a NIBIB BTRC grant to Richard Superfine, two studies by UNC Chapel Hill researchers clarify how cells respond to physical forces. This work may inform efforts to combat metastasis, in which tumor cells create mechanical stresses as they pull away from surrounding cells and pass through blood vessel walls to invade other parts of the body.
USA Today reports on an April 8 study in which 4 patients paralyzed below the chest were able to voluntarily move while receiving electrical stimulation to their spinal cords. The novel approach to rehabilitation was developed by NIBIB grantee Reggie Edgerton at UCLA. NIBIB director Roderic Pettigrew comments on the signifance of the study in the accompanying video. Watch the video and read more about the study at www.usatoday.com.
Now there may be a way of providing patients with a more focused form of chemotherapy – by using innovative “nanoballoons” and lasers. Developed by researchers at the University at Buffalo, these miniscule particles can deliver anti-cancer medications straight to the tumor itself, without causing unwanted damage along the way.

In medicine, light therapy is currently used to treat seasonal affective disorder, psoriasis, and other medical conditions, while highly targeted lasers may be used for specific skin disorders, eye diseases, or cancers. Advances in imaging methods and equipment now allow scientists to see the effects of light at the cellular level, leading to research on potentially transformative ways to use specific types of light for more even complex and direct manipulation of individual cells.
