转基因小鼠用于研究特定蛋白质在完整生命系统中的作用。然而,使用转基因小鼠研究软骨的过程带来了一些挑战。首先,许多与软骨稳态和疾病有关的因素也是胚胎发生的关键因素。因此,干预这些因素往往会导致出生前死亡,而存活下来的小鼠不能被视为正常。这些小鼠中软骨的建立被改变,使得几乎不可能真正解释蛋白质在成人软骨功能中的作用。克服这些局限性的一个好方法是使转基因小鼠具有时间和组织特异性,从而省略软骨以外的组织和胚胎学期间的副作用。本文综述了诱导软骨特异性转基因小鼠的潜在构建模块。我们回顾了哪些启动子可用于获得软骨细胞特异性-所有软骨细胞或其特定亚群-以及可用于诱导转基因的不同系统。
Transgenic mice are used to study the roles of specific proteins in an intact living system. Use of transgenic mice to study processes in cartilage, however, poses some challenges. First of all, many factors involved in cartilage homeostasis and disease are also crucial factors in embryogenesis. Therefore, meddling with these factors often leads to death before birth, and mice who do survive cannot be considered normal. The build-up of cartilage in these mice is altered, making it nearly impossible to truly interpret the role of a protein in adult cartilage function. An elegant way to overcome these limitations is to make transgenic mice time- and tissue-specific, thereby omitting side-effects in tissues other than cartilage and during embryology. This review discusses the potential building blocks for making an inducible cartilage-specific transgenic mouse. We review which promoters can be used to gain chondrocyte-specificity - all chondrocytes or a specific subset thereof - as well as different systems that can be used to enable inducibility of a transgene.
