  This important study investigates the role of Drp1 in early embryo development. The authors have addressed most of the original comments and the work now presents convincing evidence on how this protein influences mitochondrial localization and partitioning during the first embryonic divisions. The research employs the Trim-Away technique to eliminate Drp1 in zygotes, revealing critical insights into mitochondrial clustering, spindle formation, and embryonic development.

  eLife Assessment

  This is a valuable study showing that differentiated cells of the zebrafish skin form membrane protrusions called cytonemes that contact and likely transmit Notch signals to cells of the undifferentiated layer below. The data are convincing that cytoneme like protrusions from the periderm are required for proper periderm structure, proliferation, gene expression, and Notch signaling. Evidence that inflammatory signaling through IL-17 affects epidermal differentiation, Notch and cytoneme formation is solid, but whether these are through a single common or two parallel pathways requires further investigation.

  The manuscript by Ross, Miscik, and others describes an intriguing series of observations made when investigating the requirement for podxl during hepatic development in zebrafish. Understanding how genetic compensation pathways are involved in gene function is an important question. However, there is incomplete evidence provided in the manuscript at this point to conclude that discrepancies between observed phenotypes are due to genetic compensation.

  eLife Assessment

  This manuscript provides valuable insights into the heterogeneity of hematopoietic stem cells and age-associated myeloid-biased hematopoiesis. While several aspects of the study are intriguing and merit further investigation, the current results remain incomplete and additional data are necessary to substantiate the conclusions. Some of the methods and data analyses partially support the claims.
