    Optical coherence tomography captures embryonic heart dynamics
    An advanced imaging technique has both the spatial and temporal resolution to investigate the developing heart in important animal models such as chicks and mice. In studying the mechanisms that drive early heart formation, researchers rely primarily on static methods such as histology and immunohistochemistry. During cardiac looping, the minuscule heart transforms from a tubular form to a four-chambered heart, a complex process which relies upon mechanical stresses from the functioning heart for feedback. Optical coherence tomography (OCT) imaging emdash a sophisticated, noninvasive technique that can capture detailed images of biological tissue by measuring optical scattering emdash offers the ability ...
