Methods and Results—Human CD34＋primitive progenitors and CD14＋monocytic progenitors were injected locally into the ischemic limbs of diabetic mice.

方法和结果：人类原始CD34+祖细胞和CD14+单核祖细胞，通过局部注射到糖尿病小鼠缺血的四肢。

PPO gene was not detected in the multiple myelome、 malignant fibrous histiocytoma 、malignant lymphoma、malignant neurosarcoma、solitary plasmacytoma of bone、primitive neuroectodermal tumors、lipoma、 osteosarcoma and sarcoenchondroma.

PPO基因在多发性骨髓瘤、恶性纤维组织细胞瘤、恶性淋巴瘤、恶性神经肉瘤、孤立性浆细胞肉瘤、原始神经外胚瘤、脂肪瘤、骨及软骨肉瘤等肿瘤中没有表达。在骨巨细胞瘤中有微弱表达。

More materil as took from resected specimen is helpful for finding more small cell carcinoma,there is poor prognosis in small cell carcinoma concomitant with squamous cell carcinoma compared with squamous cell carcinoma alone,it is suggested that primary small cell carcinoma of esophagus might be derived from a totipotentiality primitive cell in the basal region of the squamous mucosa of the esophagus.

对手术切除标本足够取材有利于发现肿瘤的异源性成分；小细胞癌合并鳞癌者，预后较单纯鳞癌者差；本文结果支持食管小细胞癌起源于原始多潜能干细胞的观点。

Primordial germ cells derived from gonadal ridges and mesenteries of 30-70-day post menopause human ernbiyos, when cultured on mouse MEF or STO fibroblast feeder layers in presence of hrLW , hrbFGF, hrSCF, and forskolin could survive and give rise to multicellular colonies, resembLing mouse ES-like colonies .

从停经30-70天流产的早期胚胎后肠系膜中或生殖嵴部位分离到的原始生殖细胞，在小鼠的原代MEF或STO成纤维细胞等饲养层细胞上培养，能在hrLIF、hrFGF、hrSCF、forskolin等的共同作用下存活并增殖。

The result suggested that FSHR only exsited in granulosa cell and cumulus oophorus and was found in all follicle. LHR mainly exsited in granulosa cell and theca interna cell.

研究结果表明：FSHR存在于卵泡细胞和卵丘细胞，从原始卵泡开始FSHR存在于各级卵泡中。

Pancreatoblastoma is a rare pancreatic carcinoma in which. The presence of squamous corpuscles is a characteristic feature.

胰母细胞瘤是一种罕见的胰腺恶性肿瘤，鳞状小体为其特征性的组织学改变，具有多向分化的特征，其可能起源于原始多潜能细胞。

The journal publishes original research on the evaluation and characterization of teratogens, carcinogens, or mutagens; reports describing the development of novel experimental techniques for toxicological assessment, or the application of current methods in molecular and cellular biology (including in vitro studies, organ and cell culture, and the use of transgenic animals); as well as critical reviews focused on topics of significant interest to specialists in teratology, cancer biology, and mutation research.

杂志刊有关载致畸剂，致癌物质和诱变剂的评估和特征方面的原始研究；描述毒物评定的实验新技术，或当前方法在分子和细胞生物学（包括体外研究，器官和细胞培养，和转基因动物）中应用的报告；以及对畸形学，癌生物学，和突变研究中生物学家非常感兴趣课题的评论。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
