| Name: | ciliary marginal zone |
|---|---|
| Synonyms: | circumferential germinal zone, CMZ, peripheral growth zone, retinal ciliary marginal zone, retinal proliferative zone |
| Definition: | Proliferative region at the periphery of the retina where retinal stem cells are located. After 60 hpf, the CMZ is the source of most retinal growth. |

| Name: | nucleolus |
|---|---|
| Synonyms: | |
| Definition: | A small, dense body one or more of which are present in the nucleus of eukaryotic cells. It is rich in RNA and protein, is not bounded by a limiting membrane, and is not seen during mitosis. Its prime function is the transcription of the nucleolar DNA into 45S ribosomal-precursor RNA, the processing of this RNA into 5.8S, 18S, and 28S components of ribosomal RNA, and the association of these components with 5S RNA and proteins synthesized outside the nucleolus. This association results in the formation of ribonucleoprotein precursors; these pass into the cytoplasm and mature into the 40S and 60S subunits of the ribosome. |
