Methods : parenteral nutrition support was given to 10 cases 2 days after transplanting hemopoietic stem cells . their clinical improvement , body weight , increase of serum albumin and restoration of hemopoietic capacity were recorded 方法：对10例造血干细胞移植病人于移植后第2天开始给予肠外营养支持治疗，并观察临床症状改善、体重及血清白蛋白增加、骨髓造血恢复等情况。
The hla system plays an very important role in antigen identification and presentation , immune response and regulation , and is also one of the key factors that affect the result of organic transplantation and hematopoietic stem cell transplantation Hla系统在抗原识别与呈递、免疫应答与调控等方面起着极其重要的作用，是影响器官移植物长期存活和造血干细胞移植成败的关键因素之一。
Preliminary clinical trials demonstrate that fl treatment resulted in an antitumor response against human malignances and development of a variety of bioreactor systems , and results from the efficacy of ex vivo expanded hematopoietic cells for transplantation therapy 临床前实验表明， fl用于造血干细胞移植可有效地扩增体内的造血干细胞，提高机体对肿瘤细胞的主动免疫能力，为肿瘤临床免疫治疗提供了一种更为有效的治疗手段。
Myeloablative , allogeneic hsct is an effective standard therapy for specific life - threatening diseases , such as leukemia or myelodysplastic syndrome , for which blood cell lineages ( which originate principally in the bone marrow and circulate in the blood ) are abnormal 骨髓同种异体造血干细胞移植是治愈某些特殊的危及生命疾病的一种标而准有效的方法，如白血病或骨髓增生异常综合征，这些疾病的血细胞系（主要来源于骨髓并在外周血中循环）变得异常。
In contrast to murine studies , studies of human hscs have relied on a number of in vitro assays that identify cells with the capacity to generate hematopoietic progenitors in long - term culture and to differentiation into multiple hematopoietic lineages . recently , two elegant animal models that enable the in vivo measurement of human hscs marrow repopulating potential have been developed . one is the sheep in utero transplantation system in which human hematopoietic progenitor cells are transferred into the sheep fetus in utero before the development of the ovine immune system 早在80年代中期， zanjani等就利用胚胎期免疫系统发育不完善，将人的造血干细胞移植到妊娠中期胚羊腹腔内，成功地建立了人胎羊造血干细胞嵌合体移植模型，并以此实验模型作为体内检测人造血干细胞和人骨髓间充质干细胞多向分化潜能的方法。
New york ( reuters health ) jul 31 - long - term suppressie acycloir therapy in hematopoietic stem - cell transplant ( hct ) recipients can preent the emergence of herpes simplex irus ( hs ) disease , including acycloir - resistant hs disease , researchers report in the july 15th issue of the journal of infectious diseases 7月31日纽约路透社消息?研究人员在《感染性疾病》 7月15日刊中称，造血干细胞移植（ hct ）术后，受者长期应用抗代谢药阿昔洛韦，可以防止单纯疱疹病毒感染，包括阿昔洛韦耐药的hs的发生。
