Why do stem cell researchers use the mesenchymal stem cells shown in the table above for these specific types of chrondrocytes? Can you only use bone marrow to make articular cartilage, or are there other types of cartilage that can be made using bone marrow, if so which other types of cartilage?

$\begingroup$ Who is "they"? Why are certain cells in the body of different lineages than other, somewhat similar cells? Because that's how the body evolved. "Why" questions about evolution are rarely informative or helpful. $\endgroup$– MattDMoSep 11, 2016 at 15:27

$\begingroup$ @MattDMo: I was referring to stem cell researchers. For example: Can you only use bone marrow to make articular cartilage, or are there other types of cartilage that can be made using bone marrow, if so which other types of cartilage? $\endgroup$– JomansSep 11, 2016 at 15:49

$\begingroup$ OK, I see. Thanks for clarifying. You might want to add the ideas of your entire comment to the question so everyone understands. $\endgroup$– MattDMoSep 11, 2016 at 15:50
