The is a source of stem cells that has the characteristics of self-renewal and limited differentiation.

Bone marrow

Explanation:

Bone marrow is a source of adult stem cells (cells derived from adult tissue). They have the ability to self-renew but their differentiation potential is limited (they can only differentiate into cell types of the organ of their origin). So, we call them multipotent or unipotent. On the other side, embryonic stem cells can develop in any other type of differentiated cell type in the body (pluripotent). So, embryonic stem cells are more flexibile for use.

hypoxemia refers to a below usual concentration of oxygen in the blood, mainly in the arteries. hypoxemia is an indication of an issue associated with circulation or breathing and may lead to various symptoms like shortness of breath.  

the condition is identified by determining the level of oxygen in the blood sample obtained from an artery. it can also be predicted by determining the oxygen saturation of the blood with the application of a pulse oximeter.  

the normal arterial oxygen is about 75 to 100 mm hg. the values underneath 60 mm hg is generally considered with the requirement for supplemental oxygen. the normal pulse oximeter readings generally range between 95 to 100 percent. the values under 90 percent are regarded as low.  

in the given case, the oxygen saturation is measured at 93 percent, hence, there is no need to administer oxygen, that is, one should withhold oxygen.
