Zebrafish neural induction and patterning.
Appel B. Appel B. Dev Dyn. 2000 Oct;219(2):155-68. doi: 10.1002/1097-0177(2000)9999:9999<::aid-dvdy1052>3.3.co;2-b. Dev Dyn. 2000. PMID: 11002336 Free article. Review.
A goal of developmental neurobiologists is to understand the nature of the patterning mechanisms that specify neural cells for particular fates. In recent years, zebrafish has emerged as new model system for investigating vertebrate neural development, offering a unique co …

Zebrafish spinal cord oligodendrocyte formation requires boc function.
Kearns CA, Walker M, Ravanelli AM, Scott K, Arzbecker MR, Appel B. Kearns CA, et al. Among authors: appel b. Genetics. 2021 Aug 9;218(4):iyab082. doi: 10.1093/genetics/iyab082. Genetics. 2021. PMID: 34057474 Free PMC article.
In addition to its role in patterning ventral progenitors, Shh signaling must be maintained through development to specify pMN progenitors for oligodendrocyte fate. Using a forward genetic screen in zebrafish for mutations that disrupt the development of oligodendrocytes, …

CNS myelination requires cytoplasmic dynein function.
Yang ML, Shin J, Kearns CA, Langworthy MM, Snell H, Walker MB, Appel B. Yang ML, et al. Among authors: appel b. Dev Dyn. 2015 Feb;244(2):134-45. doi: 10.1002/dvdy.24238. Dev Dyn. 2015. PMID: 25488883 Free PMC article.
However, whether oligodendrocytes require cytoplasmic dynein to ensheath axons with myelin is not known. RESULTS: We identified a mutation of zebrafish dync1h1 in a forward genetic screen that caused a deficit of oligodendrocytes. ...

Through live imaging of Tg(myrf:mScarlet) and Tg(mbpa:tagRFP) zebrafish lines, both crossed with Tg(olig2:EGFP), we found that Abeta increased the number of myrf(+) and mbp(+) OLs in the dorsal spinal cord at 72 hpf and 5 dpf, respectively, without affecting total cell num …
