Caudal cell mass the inhibition of critical elements of morphogenesis, that are found in the extracellular matrix, or due to the presence of an abnormal hox gene. These abnormalities can be predicted ahead of time using ultrasound. Caudal cell mass In humans and other mammals, the caudal cell mass (sometimes tail bud in humans) is the aggregate of undifferentiated cells at the caudal end on the spine.The caudal end of the spinal cord first begins to form after primary neuralation has taken place, indicating that it develops after the cranial portion of the spinal cord has developed. Following neuralation, the caudal tail begins
