Determination of production capacity of circulated primordial germ cells (circulated-PGCs) of KUB chicken using lysis buffer ammonium chloride potassium (ACK)

Abstract

<p class="abstrak2">In poultry embryos, primordial germ cells (PGCs) are progenitor cells for gametes, which have unique migration pathway. Primordial germ cells arise from epiblast in germinal crescent and circulate through the bloodstream for a short period of time, then leave blood vessel to migrate toward gonads. The aim of this study was to determine the potential production capacity of circulated-PGCs of KUB chicken at different developmental stages of embryo using a rapid and simple method. Seventy five KUB chicken fertile eggs were divided into five groups and incubated at 38.5 <sup>0</sup>C with a humidity of 60%. Hatching was set to the embryonic development stage of 14-18. The blood was collected through dorsal aorta using micropipette under microscope. The collected blood was placed in a 1.5 ml eppendorf tube which was previously filled with 100 µl phosphate buffered saline without Ca<sup>2+</sup> and Mg<sup>2+</sup> (PBS-) mixed with fetal bovine serum (FBS) with a ratio of 90%:10%. The PGCs were purified using lysis buffer ammonium chloride potassium method. The results showed that average production of circulated-PGCs per embryo of KUB chicken were significantly affected by stage of embryonic development (P <0.05). The average production of circulated-PGCs at stage 14, 15, 16, 17, and 18 were 37.9; 53.5; 49.8; 38.3; and 33.5 respectively. The number of circulated-PGCs was not different among stages 14, 17 nor 18. The highest number of circulated-PGCs of KUB chicken was obtained at stage 15, so that the isolation and collection of PGCs through the blood circulation was recommended in stage 15.</p><strong>Key Words: </strong>KUB Chicken, PGCs, Embryonic Development Stage, Ammonium Chloride Potassium

Isolation and Number of Gonadal Primordial Germ Cells (Gonadal PGCs) on the Stages of Early Embryonic Development of KUB Chicken

“…The results of morphological characteristics of PGCs were consistent with the results reported by Kostaman et al (2013) in Gaok chicken, Minematsu et al (2004) in RIR chicken, Nakajima et al (2016) in Oriental stork and Northern Bald ibis, and Sopiyana et al (2016) in KUB chicken using the lysis buffer ACK method.…”

“…Pembekuan PGC ini sewaktu-waktu dibutuhkan dapat di transfer ke embrio resipien. Secara rinci tulisan tentang isolasi, konservasi, dan transfer dari PGC sudah dilaporkan Setioko (2008), Sopiyana et al (2008), Setioko et al (2010), Kostaman et al (2011Kostaman et al ( , 2012Kostaman et al ( , 2013, Kostaman (2014a, b), Kostaman dan Sopiyana (2014a, b, 2015c, dan Sopiyana et al (2016). Primordial germ cell yang di koleksi dari darah atau gonad embrio dapat dibekukan dan digunakan untuk menghasilkan germline chimera, serta memungkinkan pelestarian baik plasma nutfah jantan dan betina (Petitte, 2006).…”
