    1. Scope

    This document will define terminology for description of cellular and/or tissue-based products (CTPs). CTPs are primarily defined by their composition and comprise cells and/or the extracellular components of tissue. CTPs may contain cells (viable or nonviable), tissues, proteins, and other materials for which there is a rationale for benefit beyond that achievable with conventional wound coverings. CTPs may additionally include synthetic components. Whether or not an individual product is a CTP capable of promoting wound healing must be determined by adequate evidence. This guide will also describe a classification and nomenclature for CTPs based on their composition. This systematic nomenclature is not intended to be prescriptive for product labeling, and it describes only the most salient characteristics of these products; the actual biological and clinical functions can depend on characteristics not recognized in the nomenclature, and it should be understood that two products that can be described identically by the nomenclature should not be presumed to be identical or have the same clinical utility. This guide will define CTP-related terminology in the context of skin wounds. However, this guide does not provide a correspondence between the CTP composition and its clinical use(s). More than one product may be suitable for each clinical use, and one product may have more than one clinical use. This document will not purport to address safety concerns with the use of CTPs. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

    Cellular and/or Tissue based products (CTPs) are a new area of treating chronic wounds and are composed of different sources which require a Classification developed by ASTM as a standard for the industry.
