Minimum Reactants Required for Synthesis of Skin and Peripheral Nerves; Extension to Tissues of Other Organs
It is a report of the insoluble substances that went into the reactor (i.e., the anatomically well-defined defect) and the insoluble products that were eventually synthesized in it. Reaction diagram…
An Antagonistic Relation Between Wound Contraction and Regeneration
Fig. 8.1 Wounds close partly by contraction and regeneration in the tadpole; however, they close by contraction and scar formation in the adult frog. Photos of healing of full-thickness excisional…
Experimental Methods II. The Defect Closure Rule
In this example, the large difference in magnitude between the time constants suggests that the two processes (i.e., the developmental transition in healing outcome and the healing process) occur at…

Regeneration of Skin
Fig. 5.1 Structure of the intact basement membrane in skin. Top: Electron micrograph showing the two major layers comprising the basement membrane, lamina lucida (LL) and lamina densa (LD), that…
Nonregenerative Tissues
Fig. 2.1 The epidermis is a regenerative tissue. Following controlled injury (stripping or blistering), which leaves the dermis intact (left), the epidermis recovers its structure completely at the site of…
Regeneration of a Peripheral Nerve
Fig. 6.1 (Top; a): Construction of the characteristic curve for a silicone tube used as a bridge for a gap of variable length in the mouse (left) and rat (right)…
The Irreversibility of Organ Injury
Fig. 1.1 Amputation of newt limbs leads to spontaneous regeneration. Limbs were amputated either below (left) or above the elbow (right) and were photographed at the indicated times while regenerating….
