&lt;br /&gt;
刺猬信号通路是动物发育的关键调控之一，在所有的[[两侧对称动物]]中都有表达。刺猬信号通路得名于在其[[多肽]][[配体]]--Drosophila[[果蝇]]中发现的一种名为Hh 的[[细胞]]间[[信号分子]]。Hh是 Drosophila[[体节]]极性[[基因]]的表达物，是果蝇体形发育形成的基础。该[[分子]]在后期[[胚胎]]开成及变态期及起重要作用。&amp;lt;ref name=&amp;quot;Doinrg&amp;quot;&amp;gt;{{cite journal |doi=10.1038/nrg2984 |title=Mechanisms and functions of Hedgehog signalling across the metazoa |year=2011 |last1=Ingham |first1=Philip W. |last2=Nakano |first2=Yoshiro |last3=Seger |first3=Claudia |journal=Nature Reviews Genetics |volume=12 |issue=6 |pages=393–406 |pmid=21502959}}&amp;lt;/ref&amp;gt;。&lt;br /&gt;
&lt;br /&gt;
共有五种刺猬因子：音猬因子（Sonic hedgehog，SHH）、沙漠刺猬因子（desert hedgehog，DHH）、印度刺猬因子（Indian hedgehog，IHH）、Echidna Hedgehog，EHH和Tiggywinkle Hedgehog，TwHH）。仅在鱼类中发现有EHH和TwHH，哺乳类和其他动物中没有这两种刺猬因子。&lt;br /&gt;
&lt;br /&gt;
哺乳动物有三种刺猬信号路径同系物，DHH、IHH及SHH,其中Sonic研究得最深入。该路径在[[脊椎动物]][[胚胎发育]]中同样的重要。缺乏缺乏该路径组件的基因敲除小鼠，其大[[大脑]]、[[骨骼]]、[[肌肉]]系统、[[胃肠道]]及肺都未能正正常发育。近期研究表明刺猬信号路径在调节对成人组织起到维护及[[再生作用]]的[[成体干细胞]]中的作用。同样该路径也与某些[[癌症]]的发生的关系。几家制药公司正在积极的开[[发针]]通过刺猬信号[[传导]]以对抗癌症的药物。&lt;br /&gt;

[[Image:Denticlebands.png|thumb|right|'''图1.'''正常幼虫与刺猬hedgehog突变的幼虫]] 在20世纪70年代，[[发育生物学]]的基本问题是一个相对简单的[[受精卵]]是如何发展成一个复杂的身体{{le|分节|Segmentation (biology)}}的动物的。70年代末，克里斯汀·纽斯林-沃尔哈德和艾瑞克·威斯乔斯分离了控制果蝇前后[[体轴]]发育分节的[[突变基因]]&amp;lt;ref name=&amp;quot;NVW1980&amp;quot;&amp;gt;{{cite journal |doi=10.1038/287795a0 |title=Mutations affecting segment number and polarity in Drosophila |year=1980 |last1=Nüsslein-Volhard |first1=Christiane |last2=Wieschaus |first2=Eric |journal=Nature |volume=287 |issue=5785 |pages=795–801 |pmid=6776413}}&amp;lt;/ref&amp;gt;，他们的“[[饱和]][[诱变]]”技术导致了一系列参与体轴{{le|形态发生|Morphogenesis}}基因的发现。1995年，他们因在对{{le|果蝇胚胎发育|Drosophila embryogenesis}}[[基因突变]]的研究工作与爱德华·路易斯共同获得[[诺贝尔生理学或医学奖|诺贝尔奖]]。&amp;lt;ref name=&amp;quot;Nobel&amp;quot;&amp;gt;1995 Nobel Prize for discovery of [http://nobelprize.org/nobel_prizes/medicine/laureates/1995/press.html the genetic control of early embryonic development]&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The ''Drosophila'' hedgehog (''hh'') gene was identified as one of several genes important for creating the differences between the anterior and posterior parts of individual body segments. The fly ''hh'' gene was independently cloned in 1992 by the labs of Jym Mohler, Philip Beachy, and Thomas B. Kornberg. Some hedgehog mutants result in abnormally-shaped embryos that are unusually short and stubby compared to wild type embryos. The function of the hedgehog segment polarity gene has been studied in terms of its influence on the normally polarized distribution of larval cuticular [[Dermal denticle|denticles]] as well as features on adult appendages such as legs and antennae.&amp;lt;ref name=&amp;quot;Mohler&amp;quot;&amp;gt;{{cite journal |last=Mohler |first=Jym |title=Requirements for ''hedgehog'', a Segmental Polarity Gene, in Patterning Larval and Adult Cuticle of Drosophila |journal=Genetics |volume=120 |issue=4 |pages=1061–72 |year=1988 |month=December |pmid=3147217 |pmc=1203569 |url=http://www.genetics.org/cgi/pmidlookup?view=long&amp;amp;amp;pmid=3147217}}&amp;lt;/ref&amp;gt; Rather than the normal pattern of denticles, hedgehog mutant larvae tend to have &amp;quot;solid lawns&amp;quot; of denticles (Figure 1). The appearance of the stubby and &amp;quot;hairy&amp;quot; larvae inspired the name 'hedgehog'.&lt;br /&gt;
