  The manuscript represents a valuable conceptual and technical contribution to our understanding of ciliogenesis and intraflagellar transport in vertebrates. Through a series of solid and technically superb live imaging experiments to directly visualize intraflagellar transport in various zebrafish ciliated tissues, the authors unveil the surprising breadth of intraflagellar transport speed among differing organs and link this to cell type-specific differences in cilia length and intraflagellar transport train size. This work will be of broad interest to researchers in numerous fields, including development, cell biology, and imaging.

  This work presents a valuable new approach for self-supervised segmentation for fluorescence microscopy data, which could eliminate time-consuming data labeling and speed up quantitative analysis. The experimental evidence supplied is currently incomplete as the comparison with other methods is only done on a single dataset, lacks common metrics, and could not be easily reproduced for other sample data listed in the manuscript.

  This study offers valuable information on how titin derived from different nuclei within the syncytium is organized and integrated during skeletal muscle development and remodeling. The authors developed a novel mCherry titin knock-in mice with the fluorophore mCherry inserted into titin's Z-disk region to track the titin during cell fusion. The approach using mcherry adds to understanding of the role and localization of titin in controlling stiffness of striated muscles and fine tuning contraction. The results demonstrate that the integration of titin into the sarcomere is tightly regulated, with its unexpected mobility aiding in the uniform distribution of titin post-cell fusion. Although the experimental approach is convincing, the work is very qualitative in its approaches, and the data needs rigorous statistical analysis. There is a need for some clarification concerning numbers of animals and control groups. Future studies will need more rigorous data analysis and interpretation.

  This valuable study contributes to the understanding of phase separation in Dishevelled (DVL) proteins, by investigating the endogenous complexes of DVL2 using ultracentrifugation and contrasting them with DVL1 and DVL3 behaviour and the functional validation of the DVL2 intrinsically disordered regions mediating the protein condensate. The study includes a solid characterisation of several overexpression constructs, including in KO cells. However, investigations of the roles of the described DVL2 regions at the endogenous level remain to be carried out.

  This valuable paper seeks to determine the role of endogenous CNS hemoglobin in protecting mitochondrial homeostasis in hypoxia. There is merit in the work, although it remains incomplete as there is a question as to the validity of the hypoxia model as relevant to CNS-specific ischemia/hypoxia that should be considered. In particular, a whole-body hypoxia model may liberate exosomes from other hypoxic organs, which should be addressed by the authors. Overall, this work has the potential to be of broad interest to the neuroscience and hypoxia communities.

  This valuable study delineates the cellular contributions of BMP signaling in liver development and function. The findings are convincing, and the study employs state-of-the-art molecular, genetic, and cellular approaches to demonstrate that hepatic stellate cells play a central role in liver health by mediating cell-to-cell crosstalk via the production of specific BMP proteins. This study will be of interest to scientists interested in developmental biology and organ physiology.
