If you don’t have time to read all the reviews in Nature’s Regenerative Medicine Insight published May 15 or you want a preview before delving in, read these Q&As with several of the reviewers.

Ken Chien: the road ahead for regenerative medicine

Human models of human disease are likely to be the first benefits of stem cells to medicine

Sheng Ding: small molecules for stem cells

A chemical approach to regenerative medicine provides practical solutions and scientific insight.

Christine Mummery: regenerating the heart

Scientists search for the best ways to make therapies from embryonic stem cells and adult tissues.

Timm Schroeder: stem cell tracking and imaging technology

Visualization techniques are improving, but stem cells are still tough to watch

Richard Boyd and Ann Chidgey: protecting cells from immune attack

Inducing tolerance to transplanted cells could make stem-cell therapy more enduring and versatile.

Geoff Gurtner: learning healing from scars

For its power to be harnessed, wound repair must reveal its molecular secrets

Leonard Zon: unlocking stemness in haematopoiesis

After decades of study, blood still holds secrets and lessons of self-renewal

One of the best things about my job is the chance to have long conversations with enthusiastic scientists. One of the most frustrating is only being able to use one or a couple quotes from those conversations.
