Medical research in regenerative medicine and cellbased therapy has brought encouraging perspectives for the use of stem cells in clinical trials. Multiple types of stem cells, from progenitors to pluripotent stem cells, have been investigated. Among these, dental pulp stem cells(DPSCs) are mesenchymal multipotent cells coming from the dental pulp, which is the soft tissue within teeth. They represent an interesting adult stem cell source because they are recovered in large amount in dental pulps with non-invasive techniques compared to other adult stem cell sources. DPSCs can be obtained from discarded teeth, especially wisdom teeth extracted for orthodontic reasons. To shift from promising preclinical results to therapeutic applications to human, DPSCs must be prepared in clinical grade lots and transformed into advanced therapy medicinal products(ATMP). As the production of patient-specific stem cells is costly and time-consuming, allogenic biobanking of clinical grade human leukocyte antigen(HLA)-typed DPSC lines provides efficient innovative therapeutic products. DPSC biobanks represent industrial and therapeutic innovations by using discarded biological tissues(dental pulps) as a source of mesenchymal stem cells to produce and store, in good manufacturing practice(GMP) conditions, DPSC therapeutic batches. In this review, we discuss about the challenges to transfer biological samples from a donor to HLA-typed DPSC therapeutic lots, following regulations, GMP guidelines and ethical principles. We also present some clinical applications, for which there is no efficient therapeutics so far, but that DPSCs-based ATMP could potentially treat.

对于圆周运动中向心力表达式F=mν~2/r=mω~2r= m(2π/T)~2r中的r,一些学生不能够引起重视,往往简单认为它只不过是一个圆周半径而已,无需探究。但笔者在教学过程中发现,就是

对鉴赏评价的要求主要集中语言、形象、表达技巧、观点和思想内容五个方面。而前三者让学生尤感头疼,答题时出现了许多不着边际的答案,不少学生不顾题目要求,不管诗歌的实际,生搬硬套鉴赏术语,令人啼笑皆非。目前市场上充斥的各种资料,对与这三者有关的概念术语的理解也是众说纷纭,莫衷一是。如果不对其中关键术语加以明确统一,就会影响鉴赏思路和对学生答案的评判。下面就表达技巧、艺术手法、表达方式和表现手法的区别和联
阅读是人类汲取知识的重要手段和认识世界的重要途径,因此,新的课程标准下,缺少物理阅读的参与的新一轮的课程改革是不完善的,但物理阅读教学在当前的物理教学中未引起普遍重视.下面笔者根据多年的观察和教学实践,就物理阅读的现状、重要性及如何有效开展物理阅读教学,谈一点体会,起抛砖引玉的作用。
“入园难,难于考公务员;入园贵,贵过大学收费”。这是近年来广大人民群众对孩子入园问题的普遍感受。面对孩子入园的难题,很多家长甚至从孩子刚出生就开始焦虑,有的家庭发动了所有亲属,多方奔走,只为能让孩子进入自己心仪的幼儿园。    入园到底有多难    我们来看几则新闻报道:  搬马扎、支帐篷、搭行军床……为给孩子报名入园,上百名家长在北京昌平区某幼儿园门口排成了长队,队伍足足排出五六十米。队伍里一位
关于提高作文教学的效率问题,教学界普遍认为应当读写结合,以读促写,并且认可教材是最好的例子,应取法于课内。不过,怎样取法,目前看法众多。或强调在阅读中积累,或强调在阅读中练说,或强调在阅读中练写。仿习的内容涉及到仿词、仿句、仿段、仿布局、仿手法各个层面。读写结合主要依据系统论原理与迁移原理。“读”“写”是统一系统中的子系统。把他们结合起来作为一个整体来看待。教育心理学很注重学习上的迁移原理。迁移产
