Embryos of aquatic animal model fish have proven to be useful organisms for developmental biology and for early life stage toxicity tests. By virtue of their transparent chorions, imaging of normal and abnormal development can be detected and related to exposure or to alterations due to environmental factors. However, the detection of changes at sub-individual levels of organization is hampered by time required to detect important events within cells and tissues of affected organisms. We describe herein development of a highly cost effective embryo chip enabling stringent inter-individual comparisons and multiplex detection in embryos and eleutheroembryos. As a proof of principle we examine cell proliferation and controlled cell death in normoxic and hypoxic conditions and relate these to tissue turnover in individual organisms. Coupled with a recently developed whole adult animal platform, we can now move beyond the common approach focusing on single target organ to the detection and characterization of systemic phenomena (syndromes) affecting the organism. Taken together, we can now determine adult consequences of early life stage exposure and assess ability of exposed individuals to respond to stresses superimposed along the axis of time.
