Both are marked using the same vowel markers. Satellite cells express a number of distinctive genetic markers. She tests positive for more than one of the genetic markers for the disease. This led to the cluster of differentiation series of markers. Most of these markers were simply piles of stones. There are also possibilities to find the position by using coloured LED markers. Adornments serve a particular purpose across different cultures as social markers. He also worked with pastels, markers and ink. This adds more markers, and possibly different follower symbols. They were mainly employed as territorial markers and memorials (grave stones). Sesame oil studies reported a reduction of oxidative stress markers and lipid peroxidation. Later he abandoned airbrush work for pastels, markers, and ink. Researchers disagree about the usefulness of traits as invasiveness markers. Other issues relate to the sensitivity and specificity of the markers chosen. This may allow for a wider panel design and the application of new biological markers.
