求翻译：经过多年的努力，现在已经能够在体外培养组织工程骨[2,3]、软骨[4,5]、肌腱[6,14]、血管[7,8]等多种组织，部分还进行了体内实验[3,6,8]。是什么意思？

After years of efforts, now has been able to in vitro bone tissue engineering [2,3], cartilage [4,5], tendons [6,14], vascular [7,8] and other organizations were also part of the body experiments [3,6,8].

As a result of many years of effort, it is now possible to bone tissue engineering in cultivated outside the body [2, 3] and [4, 5] cartilage, tendon [ 6 ], 14, [7, 8] blood vessels, and many such organizations, some have also been carried out experiments in [3, 6, 8 ].

After many year endeavors, already could in vitro raise organization project bone [2,3], cartilage [4,5], tendon [6,14], blood vessel [7,8] and so on many kinds of organizations, the part also carry on in vivo now to test [3,6,8].

After years effort now in cultured tissue engineered bone [2,3], cartilage [4,5] or tendon [6,14], vascular [7,8] various organizations, part also in vivo [3,6,8].
