Five youngster, including Ben Tilney and Brandon Thomas-Asante, have had their options triggered by MK Dons to remain at the club for another year.
Tilney and Thomas-Asante are joined by Connor Furlong, Callum Brittain and Oran Jackson in being retained by the club.
Kabongo Tshimanga will leave the club though, and Giorgio Rasulo has signed a new deal tool.
Thomas-Asante made 12 times last season under both Karl Robinson and Robbie Neilson, and found the back of the net in the FA Cup win over Spennymoor Town.
Tilney also found the net last season, scoring a wonder-goal in his first team debut against Newport County in the EFL Cup, making 11 appearances last season.
Full-back Brittain featured in five games last season.
Both Jackson and Furlong made their debuts in the Championship season, but Jackson played just four times last season, while Furlong played once.
