“…The outgrowths in the present experiments lacked an articulation. Kao and Chang (1996) reported that dactyl, pollex, and ischium tissues of the claw of the crabs Cancer anthonyi Rathbun, C. gracilis Dana, and C. productus Randall have claw-transforming activity, based on autotransplantation of claw tissue into the autotomized stump of the walking leg. Cole (1910) pointed out that an extra claw did not develop from the middle of the outside face of the propodus, but did develop from the base of the propodus.…”

One or two wounds were made on the first cheliped of the crayfish Procambarus clarkii at a right angle from the outer lateral edge to the middle of the width of the propodus. The proximal and distal faces of the wound were kept separate with a piece of plastic. A pair of outgrowths developed on 2 of 23 chelipeds on which 1 wound was made. The outgrowths were fused at the base, but were separated distally. On 2 of 13 chelipeds on which 2 wounds were made, an outgrowth developed from each wound. On one of these chelipeds, a pair of outgrowths developed at each wound site, and each pair was fused at the base. On the other cheliped, a single outgrowth developed at each wound site. Other chelipeds with or without a piece of plastic healed normally.

“…Kao and Chang (1996) proved that dactyl, pollex, and ischium tissues of the crab claw all had claw-transforming activity if they were autotransplanted into the autotomized stump of the fourth walking leg. Furthermore, by autotransplantation of a pollex into the eye sockets, a claw with complete proximal segments (ischium, merus, carpus and manus) developed (Kao and Chang, 1997).…”

In a crayfish, Procambarus clarkii, growth of an extra claw was induced by making a V-shaped wound in the proximal end of the propodus of the second and third chelipeds. Two nerve bundles were damaged by the wounding. Some type of extra growth developed on the propodi of 13 of the damaged chelipeds: a pair of extra claws (2 chelipeds), a pair of extra dactyls (1 cheliped), a single extra dactyl (2 chelipeds), and a single slight projection (8 chelipeds). The extra claws and dactyls developed from the peripheral side of the propodus away from the wound site. One of a pair of extra dactyls and the single extra dactyls could be moved only slightly, either manually or by the crayfish. The other extra dactyls could be moved by the crayfish. Muscles were associated with each of the extra and primary claws. The muscles attached to the double extra claw or dactyl were innervated by nerve bundles that were branches from the primary thick nerve bundles. One possible explanation for these findings is that the severed nerve fibers in the thick nerve bundles regenerate, elongate into aberrant roots, and form extra claws or dactyls.

“…There are many works that concern tissue transplantation experiments on various species: Xenopus laevis and Xenopus Borealis [1,2,3,5,7,9,10,11,12,13,14,16,17,18,19,21,22,25,26,31,34,35,36], chick [15,20,32,37], Hydra attenuata [29], Cancer gracilis and other crabs [23,24]. We consider a standard paradigm: one tissue that appears in normal development (donor tissue) is transplanted to another tissue (possibly with the removal of some tissues) that appears in normal development (host tissue), then observe what the grafted tissue will develop into (host tissue, donor tissue, or neither), and whether the development is normal or abnormal.…”

We review studies on tissue transplantation experiments for various species: one piece of the donor tissue is excised and transplanted into a slit in the host tissue, then observe the behavior of this grafted tissue. Although we have known the results of some transplantation experiments, there are many more possible experiments with unknown results. We develop a penalty function-based method that uses the known experimental results to infer the unknown experimental results. Similar experiments without similar results get penalized and correspond to smaller probability. This method can provide the most probable results of a group of experiments or the probability of a specific result for each experiment. This method is also generalized to other situations. Besides, we solve a problem: how to design experiments so that such a method can be applied most efficiently.
