Caudal cell mass 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 to form a neurocele as it develops a hollow core. After this, secondary neuralation occurs in which the medullary cord begins to form and is filled with many cavities that ultimatelly form the lumen.
