Fan Yang and co-workers report on page 346 that microribbon-like, photo-crosslinkable elastomers form macroporous tissue engineering scaffolds, which facilitate cell encapsulation and cell proliferation in three dimensions. The unique geometry of microribbons leads to scaffolds with superior flexibility, which can sustain repetitive compression without failing. Such scaffolds could be particularly useful for engineering shock-absorbing tissues such as articular cartilage and intervertebral discs.
