leptotene

 [lep´to-tēn]
the stage of meiosis in which the chromosomes are threadlike in shape.

lep·to·tene

(lep'tō-tēn),
Early stage of prophase in meiosis in which the chromosomes contract and become visible as long filaments well separated from each other.
Synonym(s): leptonema
[lepto- + G. tainia, band, tape]

leptotene

/lep·to·tene/ (lep´to-tēn) the stage of meiosis in which the chromosomes are threadlike in shape.

leptotene

[lep′tətēn]
Etymology: Gk, leptos + tainia, ribbon
the initial stage in the first meiotic prophase in gametogenesis, in which the chromosomes consense and become visible as single, thin filaments. See also diakinesis, diplotene, pachytene, zygotene.

leptotene

the first stage of PROPHASE 1 of MEIOSIS in which each chromosome resembles a thin thread as it emerges from INTERPHASE. The chromosomes have divided into CHROMATIDS but these are not usually visible at this stage.

Microscope analysis: Nuclei of the first meiotic prophase at leptotene, zygotene and pachytene stages were analyzed using a Zeiss Axioskop epifluorescent photomicroscope equipped with propidium iodide, fluorescein isothiocyanate, and 4,6-diamidino-2-phenyllindole filters (Carl Zeiss, MC80, Oberkochen, Germany) equipped with an epifluorescent system.
Statistical analysis: Mann-Withney test was used in order to evaluate the frequencies of leptotene, zygotene, and pachytene stages, and the staging of pachytene cells in controls and patients.
Respective frequencies of leptotene, zygotene and pachytene stages: In the controls, the frequency of leptotene stage (Fig.
In patients, the frequency of leptotene stages varied from 2 to 11.
Much less frequent were the leptotene and zygotene stages.
In meiosis the process is divided into six stages: preleptotene, leptotene, zygotene, pachytene, diplotene, and diakinesis.
The chromatin appears as a very dense cluster in the leptotene spermatocyte.
